Electrical Switches price comparison UK
Rotary isolators, smart switches, ceiling switches, industrial disconnectors — the electrical switch category is far broader than most buyers expect. Our catalogue spans 182 products, from a basic Legrand wall switch at 0 £ to a heavy-duty ABB 4-pole rotary isolator pushing close to 0 £. That range tells you something important: you need to know exactly what you're switching before you start comparing prices.
Eaton dominates the catalogue with 58 references, mostly industrial-grade rotary and cam switches rated for three-phase applications. Schneider Electric comes in second with a notably lower average price point, covering everything from simple ceiling switches to industrial push-button assemblies. Siemens and ABB round out the industrial tier, while Shelly has carved out a distinct niche with its Wi-Fi-enabled smart switches — compact modules that retrofit into existing back boxes and integrate with home automation platforms. It's a genuinely different product from a 63A rotary isolator, yet both sit in this category.
One pattern worth flagging: the gap between the median price (0 £) and the third quartile (0 £) is relatively narrow, which suggests the mid-range is well-stocked and competitive. The real price jumps happen at the top end — ABB's high-amperage 4-pole units are in a different league entirely, and rightly so. For most domestic or light commercial buyers, the sweet spot sits comfortably below 0 £.
If you're sourcing for a control panel or industrial enclosure, also check our Electrical Relays and Electrical Switch Accessories categories — mounting adapters, legend plates, and auxiliary contacts are frequently needed alongside the switch itself. For smart home applications, Light Switches may offer a more targeted selection. We track prices daily across Currys, Amazon.co.uk, and specialist electrical wholesalers, so the figures you see reflect the current market — not last month's stock.
How to Choose the Right Electrical Switch
Pick the wrong switch and you're not just looking at a return — you're potentially looking at a failed inspection or a fire risk. With products ranging from a simple 1-gang ceiling switch to a 4-pole 63A rotary isolator, the first question isn't about brand or budget. It's about what the switch actually needs to do.
Poles and phases: match the switch to your circuit
A 1-pole switch controls a single live conductor — fine for a standard domestic lighting circuit. Step up to a 3-phase motor or industrial machinery and you need a 3P or 4P switch that breaks all live conductors simultaneously. Using a 1P switch on a 3-phase circuit isn't just wrong — it's dangerous. Check your installation's phase configuration first. Most of the Eaton and Siemens units in this catalogue are 3P, which tells you where the bulk of demand lies.
Amperage rating: size it for the load, not the cable
The amperage rating must exceed the maximum current the circuit will ever draw — including motor start-up surges, which can be 5–7× the running current. A 32A switch on a circuit that peaks at 40A during motor start will degrade rapidly. Common ratings here run from 6A (light domestic) through 16A, 32A, 50A, up to 63A and beyond for heavy industrial use. Don't undersize to save money; the replacement cost and downtime will far outweigh any initial saving.
IP rating: how hostile is the environment?
IP20 is adequate for a dry indoor panel. IP54 handles splashing and dust — suitable for light industrial or garage use. IP65 is the minimum for outdoor enclosures or washdown environments. The Schneider Electric ceiling switches in this catalogue are typically IP20 domestic units; the industrial rotary switches from Eaton and Siemens often reach IP65. Fitting an IP20 switch in a damp utility room is a common and costly mistake.
Mechanism type: rotary, toggle, or smart?
Rotary cam switches (the red-and-yellow handled units from Eaton and Siemens) are the industrial workhorse — robust, tactile, and rated for hundreds of thousands of operations. Toggle and lever switches suit control panels where quick visual confirmation of state matters. Smart switches (Shelly, Fibaro) are a different animal entirely: they sit behind your existing switch plate, add Wi-Fi or Z-Wave control, and cost from around 0 £. They're excellent for retrofitting home automation without rewiring, but they require a neutral wire in most configurations — check before buying.
Switching category (AC-15, AC-23): the spec most buyers ignore
The switching category defines what type of load the switch can handle safely. AC-15 covers electromagnetic loads up to 72VA — light contactors, solenoids. AC-23 is rated for motor starting and stopping, which involves much higher inrush currents. Fitting an AC-15-rated switch on a motor circuit will cause premature contact wear and eventual failure. This spec is buried in the datasheet but it's non-negotiable for industrial applications.
Certifications: CE is the floor, not the ceiling
Any switch sold in the UK must carry CE marking (or UKCA post-Brexit for UK-manufactured goods) and comply with IEC/EN 60947-3 for industrial switches. For domestic installations, BS EN 60669 applies. Which? and BEAB approval add consumer confidence for residential products. ABB, Eaton, Schneider Electric, and Siemens all carry the relevant industrial certifications — it's one area where buying from a recognised brand genuinely matters, particularly if the installation will be subject to a Part P inspection.
- Entry-level and basic switching (From 0 £ to 0 £) : Simple 1-gang ceiling switches, basic rotary selectors, and smart switch modules like the Shelly 1 Mini Gen3 live here. Ospel and Legrand dominate the lower end with straightforward domestic units. Perfectly adequate for lighting circuits and low-current applications, but don't expect industrial IP ratings or high amperage capacity.
- The practical mid-range (From 0 £ to 0 £) : This is where most buyers land. Schneider Electric's rotary switches and Siemens 3P isolators sit in this band, offering genuine industrial-grade performance without the premium. The Shelly 2PM Gen3 smart switch also falls here — a strong option for home automation. Good IP ratings, proper certifications, and enough amperage for most commercial applications.
- Industrial and specialist (From 0 £ to 0 £) : Eaton's cam switches and Berker controller switches occupy this tier. You're paying for higher amperage ratings, better cycle life, and more robust housings. Suitable for machinery isolation, control panel integration, and environments where the switch will be operated frequently. Legrand and Merten also appear here with more specification-heavy products.
- Heavy-duty and high-specification (Over 0 £) : ABB's high-amperage 4-pole rotary isolators and Schneider Electric's advanced assemblies push into this territory. These are not general-purpose products — they're specified for large motor loads, main isolator duties, and applications where failure is not an option. ABB's top unit approaches 0 £. If you're here, you likely already know exactly what you need; the value of comparing prices across suppliers is significant at this level.
Top products
- Schneider Electric VCF01 electrical switch Rotary switch 3P Black, Red (Schneider Electric) : The most accessible 3P rotary switch in the catalogue — solid Schneider build quality at a price that undercuts Eaton and Siemens equivalents. A strong default choice for light industrial isolation duties, though check the amperage rating carefully against your load.
- Eaton P1-32/V/SVB Rotary switch 3P Red, Yellow (Eaton) : Eaton's P1 series is a workhorse — 32A, 3-pole, with the distinctive red-yellow handle that signals proper isolation. Well-suited to machinery and control panel use. Not the cheapest 3P switch here, but the build quality and cycle life justify the premium over budget alternatives.
- Siemens 3LD2203-0TK53 3P Red, Yellow (Siemens) : Siemens' answer to the Eaton P1 — comparable spec, competitive price, and the same reassuring red-yellow handle. Worth comparing directly against the Eaton; the price difference between the two can vary by retailer, making this a genuine alternative rather than a compromise.
- Shelly 2PM Gen3 Smart switch 2P Black (Shelly) : The standout smart switch in this catalogue. Two independently controlled channels, power monitoring, Matter support, and local API access — all in a module that fits a standard back box. Excellent for home automation retrofits. Requires a neutral wire; not suitable for high-current industrial loads.
- Schneider Electric Exclusive - 2-pole 1-way ceiling switch - 1 gang - 50 A - white (Schneider Electric) : A 50A ceiling switch at a very accessible price — one of the better-value domestic/light commercial options in the range. The 2-pole configuration suits shower and cooker circuits. Straightforward, certified, and from a brand with proper after-sales support. Nothing flashy, but exactly what it needs to be.

Frequently Asked Questions
What is the difference between a 3P and a 4P electrical switch?
A 3P (3-pole) switch breaks three live conductors simultaneously, which is standard for three-phase circuits. A 4P (4-pole) switch also breaks the neutral conductor, providing complete isolation — required by some regulations when the neutral must be disconnected for safety, such as in certain industrial and medical installations. For most three-phase motor applications, 3P is sufficient. If in doubt, consult your installation's wiring diagram or a qualified electrician.
Can I use a Shelly smart switch to replace any existing wall switch?
Not always — the most common obstacle is the absence of a neutral wire. Most Shelly modules (including the Gen3 range) require a neutral at the switch position, which older UK wiring often lacks. The Shelly 1 Mini Gen3 has a no-neutral mode, but it can cause LED flicker with some lamp types. Always check the wiring at your back box before purchasing. Also confirm your router's Wi-Fi band: Shelly devices connect on 2.4GHz only.
What IP rating do I need for an outdoor or garage installation?
For a covered outdoor location or a dry garage, IP44 is the practical minimum. For direct exposure to rain, jets of water, or dusty workshop environments, specify IP65 or above. IP20 domestic switches — common in this catalogue — must never be used outside or in damp utility rooms. The Eaton and Siemens industrial rotary switches in this range typically carry IP65, making them suitable for outdoor plant rooms and agricultural buildings.
Are cheap electrical switches from lesser-known brands safe to use?
It depends entirely on the application and the certifications present. A CE-marked switch from a smaller brand is legally compliant for sale in the UK, but CE self-certification means the manufacturer declares conformity — it isn't third-party verified. For domestic lighting circuits, a reputable brand like Legrand or Schneider Electric at a modest price is a safer choice than an unknown import. For any industrial or high-current application, stick to brands with IEC 60947-3 certification and traceable test data — Eaton, Siemens, ABB, and Schneider Electric all meet this standard.
What does AC-23 mean on a rotary switch, and does it matter?
AC-23 is a utilisation category defined by IEC 60947-3, specifically for switching motors — including starting and stopping under load. It's a significantly more demanding rating than AC-21 (switching resistive loads) or AC-22 (mixed loads). It matters enormously: fitting an AC-21-rated switch on a motor circuit will cause accelerated contact erosion and premature failure. All the Eaton and Siemens 3P rotary switches in this catalogue are rated AC-23, which is why they're priced above basic toggle switches.
How many electrical switches do you compare, and how often are prices updated?
We currently list 182 electrical switches across the catalogue, with prices updated daily from multiple UK and European retailers. The range spans from 0 £ for basic domestic units to 0 £ for heavy-duty industrial isolators. Prices can shift significantly around Black Friday and January sales, particularly on Schneider Electric and Eaton products — it's worth setting a price alert if you're not buying immediately.
Is it worth buying a smart switch like Shelly or Fibaro in 2026?
Yes, for most home automation retrofits — but the value depends on your ecosystem. Shelly's Gen3 range offers excellent value, with local API control and Matter support reducing dependency on cloud services. Fibaro's Z-Wave switches cost more but integrate tightly with dedicated home automation hubs and offer superior range through walls. If you're already using a platform like Home Assistant, Shelly is the pragmatic choice. If you're invested in a Z-Wave or Zigbee hub, Fibaro justifies the premium.
