In every electrical appliance or electronics, one of the major additions is a switch. Without a switch, there is no way you can operate an appliance. Every appliance has its own usage of the switch and has different types attached to them. Read more to find out more about them and how to choose the best for a certain appliance.

What are the Switches?

Electrical switches, in the simplest way, can be explained as a device that regulates the flow of electricity in a circuit. Every appliance has a circuit that delivers electricity to it, which makes the appliance on and off. To make the on and off easy, switches are installed. They work on a binary mode, that is, it is either completely on or completely off. There are several types that one can choose from based on their application and ease of usage.

Popular Switches Types

There are several types of switches out there. Here, let’s discuss some of the most popular ones in the category.

  1. Slide: these are used in small and simple electrical projects and appliances. In this, the switch slides from off to on point and vice versa to control the flow of the electricity.

  2. Toggle/ rocker: these are easily recognized as the ones which are used in the household switchboards. These have an angled lever which keeps the switch in an angled position of on and off.

  3. Door switch: these are very common in restricted places like hospitals and vaults. These are attached to the door frame and closing and opening of the door act as the on and off or the circuit.

  4. Pushbutton switch: pushbutton switches are quite common in smaller electrical appliances. In this, the switch is pressed to switch on and off the circuit. In some cases, the button comes back to the original position and in some, it stays at on or off position till it is pressed again.

  5. Limit switches: in these, an actuator plunger is utilized to change the way the electrical circuit is in. When the switch comes in contact with a moving object the switch turns from on to off or vice versa.

  6. Pressure switches: these are very popular in the security alarms and pressure floors. In this, a fluid set pressure is a reason which makes the circuit open or closed. As soon as the pressure is reached the circuit closes or opens.

How to choose a Switch?

Above mentioned are some of the common switches that are used in electrical appliances. However, to find a good switch, few things should be kept in mind like:

  1. Type: the very first thing is to decide what type of switch is to be utilized. It can depend on the objective, appliance, and electrical power that is to be regulated.

  2. Material: one should be careful while picking the switches, as it will decide whether the appliance will be safe or not. The switches should be made of higher quality material to avoid any accidents.

  3. Longevity: switches should be made of good quality so that it can be used for a longer time without any damage.
