The details of the product does not make clear that it's fine to use this for low voltage applications, but it certainly is (and has worked as above in my caravan really well). It's a very solid bit of kit too and is easily fitted and looks great when installed. Many reviewers here state the instructions too basic to understand, but I can't really see this argument given a simplistic yet idiot proof diagram is provided showing exactly what switching connections are achieved in the three switch positions (the mid position denoting all connections being off). It's a bargain and I'm really pleased... Review: Good quality with easy to use connector spades supplied - Am using this to switch supplies to garden lighting between On, Off and PIR-switched. Simple to fit in a softwood box with c 5mm walls but I needed to use shorter bolts than supplied for this shallow depth. These are the four small M5 bolts that penetrate the mounting surface to attach the face plate. Best to solder wires to the supplied connection spades. I tried crimping at first unsuccessfully – I don't think it's designed for crimping: what look like crimping tags on the spades I think instead are there to hold in place the insulation sleeve, which they do well. I wired up this switch easily, feeling confident the connections were both tight and well insulated. I needed a circuit tester, and pen and paper to quickly sketch out how the switch worked and how to wire its terminals for my purposes. ## Features - Model:SZW26-20/D202.2;Material:Plastic & Electronics - Ui : 660V ; Ith : 20A - Positions: 3 Positions(1-0-2) - Size: 50 x 50 x 70mm /2" x 2" x 2.8"(L*W*T) - Net Weight: 89g ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07L8SJXGV | | Actuator Type | Rotary | | Best Sellers Rank | 9,251 in Business, Industry & Science ( See Top 100 in Business, Industry & Science ) 3 in Selector Switches | | Brand | Heschen | | Circuit Type | 3-way | | Colour | Blue | | Connectivity Protocol | Wi-Fi | | Connector Type | Screw Terminals | | Contact Material | Brass | | Contact Type | Normally Open | | Control Method | Push Button | | Controller Type | Mechanical knob | | Country Of Origin | China | | Current Rating | 20 Amps | | Customer Reviews | 4.6 4.6 out of 5 stars (2,737) | | International Protection Rating | IP20 | | Item Dimensions | 7.3 x 3.7 x 3.7 centimetres | | Item Weight | 0.13 Grams | | Manufacturer | SL | | Material | Plastic | | Model Number | SZW26-20/D202.2 | | Mounting Type | Surface mount or panel mounting | | Number of Items | 1 | | Number of Positions | 3 | | Operating Voltage | 660 Volts | | Operation Mode | ON-OFF-ON | | Specification Met | CE, IP20 | | Switch Type | Rotary | | Terminal | Screw | | UPC | 670534181324 | | Unit Count | 1 count | | Wattage | 13200 watts | ## Product Details - **Brand:** Heschen - **Connector type:** Screw Terminals - **Contact type:** Normally Open - **Current rating:** 20 Amps - **Item dimensions L x W x H:** 7.3 x 3.7 x 3.7 centimetres - **Material:** Plastic - **Operating voltage:** 660 Volts - **Operation mode:** ON-OFF-ON - **Switch type:** Rotary - **Terminal:** Screw ## Images ![Universal Rotary Cam Selector Changeover Switch SZW26-20/D202.2 660V 20A ON-OFF-ON 3 Position 2 Phase 8 Terminals - Image 1](https://m.media-amazon.com/images/I/71RTLaPi1XL.jpg) ## Questions & Answers **Q: Could this be used to select between powering two appliances that I never want to use at same time, so avoiding ever tripping breaker** A: Absolutely, I used this to power an electric gate switching between solar and mains power. I had two power supplies powering one product, You're just doing the reverse, one power supply to two products. **Q: Why are there no instructions or proper wiring diagram?** A: Laziness and cost savings of manufacturing the world over. It doesn't matter what you buy these days very few instructions are included. It is easier for the buyer to look them up on the net and print them out their selves. Have wasted many hours doing this. That's about all the help I can give. **Q: Can I use this to switch between mains 240v and inverter in a motorhome?** A: Yes, I used it to switch from shore power to inverter power, 1 input from shore, 2 input from inverter, output to consumer unit. **Q: Can anyone recommend a larger back box for this swith (I need 2x2.5mm input cables and 2x outputs), the ones I see only have space for 2.** A: If you have the correct holesaw and an Hss drill for the fitting set screws you can fit this to any deep, IP rated surface box with a flat surface ## Customer Reviews ### ⭐⭐⭐⭐⭐ Not clearly defined, but fine for switching low voltage 12v circuits too. *by I***E on 13 July 2024* Used to alternately switch power between two 12v TVs from a single power stabiliser adaptor.
