What is a momentary push button switch?

Momentary push button switch When a finger presses the head of the push button switch, the spring board in the push button switch presses down the spring. At the same time as the spring presses down, the silver point on the spring board is in contact with the silver point on the base. When the power is turned on when the finger leaves the button, the spring inside the button bounces immediately, the silver dot on the springboard is separated from the silver dot on the base, the button switch will be disconnected, and the machine will stop working.
