Does the metal button switch have self resetting and self-locking?

Metal push button switches can be divided into two types: self-resetting (Momentary) and self-locking (Latching):

1. **Momentary Switch**:
- This switch closes a circuit when pressed and opens the circuit when released. It is often used in situations where short-term control is required, such as starting, stopping or instantaneous signal sending.

2. **Latching Switch**:
- This type of switch closes a circuit when pressed, and when released the circuit remains closed until the switch is pressed again. Ideal for applications where state maintenance is required, such as power switches or function switches on control panels.

Choosing the appropriate switch type depends on the specific application needs and mode of operation.
