Wiring methods of metal push button switches

1. Normally open wiring method: In this way, when the button is not pressed, the circuit is in an open state. After pressing the button, the circuit is connected. Usually, one end of the power supply is connected to one terminal of the normally open contact, and the other terminal is connected to the load. The other end of the load is then connected to the other end of the power supply.

2. Normally closed wiring method: In normally closed wiring, when the button is not pressed, the circuit is connected. After pressing the button, the circuit is disconnected. Generally, one end of the power supply is connected to one terminal of the normally closed contact, and the other terminal is connected to the load. The other end of the load is connected to the other end of the power supply.

3. Compound wiring method: The compound wiring method combines normally open and normally closed contacts. In this way, there are two sets of contacts, one set is normally open and the other set is normally closed. Wiring can be done according to specific control requirements to achieve different circuit functions. For example, the normally open contact can be used to start a certain device in one circuit, and the normally closed contact can be used to stop another device.
