A Beginner’s Guide to Buying High Voltage Rotary Switches

Many people have to make the decision of whether or not to buy rotary switches for their electronics projects, but few know exactly what to look for when they do. It can be confusing choosing between single-pole and double-pole switches or what size switch to buying in the first place, especially when you consider how many other variables there are when it comes to electronics projects. This article aims to help you figure out which rotary switch is right for you and what size switch you should get depending on your needs.

What are rotary switches? A rotary switch, or rocker switch, is a device that consists of a knob attached to a spring-loaded centre shaft with multiple electrical contacts at each end. Rotary switches are used in applications where it’s desirable to control one circuit with an input device that has an integral momentary contact rating. They typically come in multiple sizes and patterns (SPDT, DPDT) and are often rated for high voltage and current. There are two main styles of rotary switches: on-off and rocker. On-off switches look just like you’d expect a switch to look, with three prongs sticking out of a central contact. Rocker switches have one rocker arm that usually pops out perpendicular to where it’s mounted; they are most commonly used in electronics projects. The difference between on-off and rocker switches is an important one, but it will vary by project.

The toggle switch, the rocker switch, and the slide switch are the three most prevalent types of rotary switches. A toggle switch consists of three terminals that slide vertically along a single piece of metal in an upward and downward motion. Slide switches are characterized by having two terminals that are able to move along a rail. Rocker switches each have one terminal that can move in either direction along a piece of metal that can rock back and forth.

You’ll find rotary switches on everything from appliances, lights and electronics to industrial machines, so they are a common sight in most homes. The most common places you can buy rotary switches are from home-improvement stores or electronic websites. They’re pretty inexpensive, so you don’t really need to shop around too much to find a good deal. If you’re having trouble locating these items in your local area, check out an online store for even more selection and savings. The process of buying rotary switches is as easy as locating a site that has what you want and adding it to your cart.

The vast majority of rotary switches are utilized in two-way wiring configurations, in which a switch is installed at both the beginning and the end of a wire circuit. Each switch, in this case for an LED light fixture, is connected to a light fixture by a pair of cables. Even though there are three wires going out of each switch box, some rotary switches can be used in three-way circuits. However, it is recommended that you pick a switch that is rated specifically for the type of wiring that will be utilized.
