There is an incorrect review here (for the Taiss LW26-20 0-5/3 switch) which may be for another switch in the Taiss line. This switch behaves exactly the way the diagram in the listing shows and has no internal jumpers nor are any of the terminals strapped. Individual pairs of terminals 1-2, 3-4, 5-6, 7-8, and 9-10 are shorted one pair-at-a-time depending on the switch position with terminals 11-12 never being connected or affected by switch position (these are isolated and can be used as connection points). Position 0 leaves all terminals disconnected. As best as can be determined, connections are break-before-make which means one terminal set is disconnected before any other is connected (that description posted elsewhere is a bit confusing). The switch is listed to have silver plated contacts which is another plus if true. These switches are designed for heavy currents but will work for lower currents just fine. The switch operates with little effort and has clean detents for each position. Mounting is achieved by removing the knob and first panel (the one with printing). The small transparent cover and printed layer then pops out and screws pass through the holder and into bolts in the switch body section to sandwich the mounting panel (needs to be drilled with 4 corner holes (approximately 36.2mm center-to-center in a square pattern) between it and the switch body. These screws tighten and then the printed cover is replaced along with the knob, giving the mounted switch an excellent cosmetic appearance and sturdy mounting. Terminals and mounting screws are included, making this a good packaged product. There are no instructions provided with the switch itself, so the listing and the switch terminal connection diagram (shown with this review) are important to note though these can be deciphered fairly easily with a continuity tester. For this price, you get a heavy duty switch which appears to operate well and does exactly what it's supposed to do. Review: Good Switch. Documentation Could Be Better, But It Works. - Important to Note: Terminals 2 & 4 are tied together, internally, and Term's 6 & 8 are tied together, internally. The diagram shows this as "1 Phase" and "2 Phase". These connections cannot be removed. There is also a supplied (removable) jumper, installed between Term's 4 & 6, which effectively ties all the even-numbered terminals together. If using a "common" supply (e.g., one input, with four selectable outputs), then leave the jumper in (between 4 & 6) and supply any one of the EVEN side terminals with your "common" supply power. Then the ODD numbered terminals will be switched ON in sequence, as the switch is rotated, as follows: Position 0 (zero) everything is OFF. Position 1: turns on terminal #1 only. Position 2: turns on Term. #3 only, #1 goes OFF. Position 3: turns on Term. #5 only, #3 goes OFF. Position 4: turns on Term. #7 only, #5 goes OFF. In addition, all of the contacts are "Break before Make", so there is "overlap" of the outputs (one turns OFF before the next turns ON). This is a decent rotary switch. It rotates easily without much force, but has good, firm detents in each position. The handle/knob is decently sized, and is easy to operate. I used the 4-position/8-contact unit, along with the small "Baomain" matching enclosure (sold separately, also on desertcart) as the selector switch for a remote, multi-port RF amplifier selector box. It operates remote relays that switch between 1 of 4 different radio amplifiers, using a 12-volts DC supply. Works very well. ## Features - Product name: 5 Position Changeover Selector Switch,Model: LW26-20-4/2 - Action Type: latching; positions: 5 positions(0-1-2-3-4); 8 terminals - Ui: 550V, Ith: 20A; Uimp: 3KV;Total size:48x48x72mm/1.8"x1.8"x 2.8"（l * w * h） - Material: Flame retardant PC material, high temperature resistance; copper parts with silver alloy point,have Good conductivity and oxidation resistance - Package content: 1xChangeover Selector Switch+8pcs SV2-4 Blue Terminal+4 x Mounting Screws ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08GR2344M | | Actuator Type | Rotary | | Best Sellers Rank | #27,750 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #8 in Selector Switches | | Brand | Taiss | | Circuit Type | 5-way | | Connectivity Protocol | X-10 | | Connector Type | Screw | | Contact Material | Silver | | Contact Type | Normally Open | | Control Method | Touch | | Current Rating | 20 Amps | | Date First Available | August 27, 2020 | | International Protection Rating | IP54 | | Item Weight | 3.84 ounces | | Item dimensions L x W x H | 1.97 x 1.97 x 1.97 inches | | Item model number | 20A 550V | | Manufacturer | Taiss | | Mounting Type | Surface Mount | | Number of Items | 1 | | Number of Positions | 4 | | Operating Voltage | 550 Volts | | Operation Mode | ON-OFF | | Product Dimensions | 1.97 x 1.97 x 1.97 inches | | Terminal | Screw | | Unit Count | 1 Count | | Wattage | 11000 watts | ## Product Details - **Brand:** Taiss - **Connector Type:** Screw - **Contact Type:** Normally Open - **Current Rating:** 20 Amps - **Item dimensions L x W x H:** 1.97 x 1.97 x 1.97 inches - **Material:** Copper - **Operating Voltage:** 550 Volts - **Operation Mode:** ON-OFF - **Switch Type:** Rotary, Temperature Switch - **Terminal:** Screw ## Images ![Taiss Universal Changeover Switch 20A 550V 4 Position 8 Terminals Latching Rotary Cam Selector Switch + SV2-4s Blue Connection Terminal LW26-20 0-4/2 - Image 1](https://m.media-amazon.com/images/I/71XTO-NowLL.jpg) ## Available Options This product comes in different **Size, Style** options. ## Questions & Answers **Q: I have two hots going into my breaker box (240volts). I want to put this switch before it reaches power to the box so I can cut power completely?** A: Without me being able to see it, I don’t know how you would get 240 v from it. I can see how you could get 120 v from each switch but to have 240 v, I’m sorry but I don’t know the answer. **Q: How do you attach the face plate?** A: If you look close at the picture you can see a screw in the knob and two black “plates.” Remove the screw and knob and then you can put a plate on either side of whatever you are installing the switch on and put the knob and screw back in. I bought the box in the “frequently bought together” section on Amazon too. Baomain Master Switch Exterior Box SZW26-20 Work for Cam Switch SZW26-20/0-3.2 660V 20A 4 Position I hope this helps **Q: I want to run a series of 20 amp rectifying diodes around a rotary switch to adjust voltage to a 12vdc, 250 watt motor. Will this switch work?** A: This should work for what you explained. **Q: can I use it to switch from charging 2 12v batteries in parallel to using my 24 v trolling motor in serial?** A: Trolling motors can draw a lot of amperage, make sure you spec it correctly ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good Switch Design and Construction *by R***. on November 11, 2025* Nice switch for the price.

Used 12awg, 36v, semi-outdoors, works nice. ## Frequently Bought Together - Taiss Universal Changeover Switch 20A 550V 4 Position 8 Terminals Latching Rotary Cam Selector Switch + SV2-4s Blue Connection Terminal LW26-20 0-4/2 - Chtaixi DC Miniature Circuit Breaker, 2 Pole 500V 100 Amp Isolator for Solar PV System, Thermal Magnetic Trip, DIN Rail Mount, High Current DC Disconnect Switch MCB 2P C100 - Chtaixi AC Miniature Circuit Breaker, 25 Amp 120V/240V 2 Pole DIN Rail Mount Circuit Breaker, Thermal Magnetic Trip, Solar AC Disconnect Switch MCB C25 --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.be/products/236899077-taiss-universal-changeover-switch-20a-550v-4-position-8-terminals](https://www.desertcart.be/products/236899077-taiss-universal-changeover-switch-20a-550v-4-position-8-terminals) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-04-22*
