## Overview

The Taiss Universal Changeover Switch is a professional-grade 5-position rotary selector switch rated for 20A and 550V, featuring flame-retardant PC material and copper-silver alloy terminals for durability and conductivity. Designed for versatile electrical control applications including motor and circuit switching, it offers smooth, secure switching with break-before-make contacts and comes with all necessary mounting hardware for easy installation.

## Description

Positions: 3 (0-1-2-3-4) Terminals: 8 Positions 1: 1-2 Position 0: All terminal undisconnected Position 2: 3-4, Position 3: 5-6, Position 4: 7-8 Model: LW26-20-4/2 Ui: 550V Ith: 20A Action Type: Latch Ideal for Electric selection power switches, speed wiring for switches and asynchronous motor and reverse gear, also can convert the control circuit. Widely used as circuit control switches, testing equipment switches, motor control switches and main control switches, signal transfer switches or replacement switches for electric welding machines and other equipment.

With flexible handle conversion, the rotary selector is easy to control, the square plate and screws can be easily mounted.

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.
Review: The wiring diagram is wrong and the knob screw is radically too short - If you really need to switch 4 pairs of contacts, this isn't for you. The switch I received has 4 of the contacts common, and simply switches continuity to each of the other 4 contacts individually one at a time (or to none at all, at 0). This works fine for me, and saves me the step of jumpering all the commons (I'm switching one common line among 4 potential outputs). The other issue is that the screw that holds the knob to the selector shaft is comically short. In a piece of notebook paper it might get enough purchase to hold, but in an 1/8" panel it barely bites and mounted in a piece of 1/4" ABS it can't even feel the female threads of the shaft. So I'm going to have to order this tiny silly metric screw from McMaster. Other than those issues, it seems well made and is working fine so far.

## 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.

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
