control device
Control devices are an important component of the electrical world. Any electrical load must be controlled. By control we generally mean keeping something within one’s possession or creating an opportunity to use it when needed.
Switches and circuit breakers are usually used as control devices in electrical systems. The method of connecting and disconnecting loads in electrical circuits is called control. Generally switches and circuit breakers are used more I The method of connecting and disconnecting the load in an electrical circuit is called control I All the devices that can be used to turn on and off the current flow in the circuit are called control devices.
Importance of control devices:
Control device is very important for proper use of load in electrical system. The reason is that if there is no control device, then if any load is switched on in the electrical system, it would only be on and if it is switched off, it would only remain off. If there is a control device, it can be used according to the need. For example, the fan is not needed in winter, so the fan is kept off. During the day, not much light is needed, so the light switch is kept off.
A circuit without a control device is not safe. Therefore, control devices are used in every field of power transmission and distribution system. So the need for control instruments is immense.
Control devices are – SPST Switch, Push Switch, Knife Switch, Circuit Broker, Rotary Switch, Intermediate Switch.
