PUSH BUTTON SWITCH

The Structure

It is composed of button cap, reset spring, fixed contact, movable contact, housing, pillar connecting rod, etc.

◀ Start Push Button :  When the button cap is pressed down, the contact is closed. And the contact is automatically disconnected and reset after released.
