Door Switch Application Principle

A switch determines the circuit by the displacement of an object, which is called the door switch. In our diary life, the most obvious example is the refrigerator. The lamp lights up when you open the refrigerator. Conversely, the lamp shuts down. Because there’s a switch on the refrigerator door frame, the door switches can be used in other appliances, such as the washing machine. 

The speed is high during the dehydration of the washing machine. If someone accidentally opened the washing machine door, then put your hand into it. It’s straightforward to harm people. That’s a reason why install the electric contact and door switch. 

Once someone opens the washing machine door, the motor will be cut off, and you have to do it mechanically. The door has been opened as soon as it brakes to stop the rotating part to avoid hurting the people.
