In addition to the common switches used for switching off electrical appliances used in electrical systems, there are several types of electrical switches used for special purposes and control of even particular electrical equipment. Is an electrical system, here we will go together to find out.

1. Heavy load switch
Used mainly to control large capacity appliances such as hot water cylinders, electromagnetic cookers, refrigerators, etc. Large load-carrying switches are an alternative to conventional CBs because of their design. Compact, suitable for interior space easily placed wall with the same as the resistance against overvoltage, anti-short circuit. Typically, the switches usually have the name of the product it controls. For example, the switches used for the water heater usually have the words “water heater” and on the switch there are usually lights.
