The Principle Of Metal Push Button Switch

The principle of metal push button switch can be divided into two types:

1. The working principle of the metal push button switch depends on its structure:

The metal push button switch with light is mainly divided into five parts: elastic, base, cover, button and pin. Here the button is the external force; The spring is a key part of the metal button switch with the light, the switch opens and closes, the shrapnel is caused by the change of force; The pin refers to the junction of the luminous metal key switch and circuit, generally has five pins, two or two sets, a pin is used to ground, when asked with the normal force of four pins open, the circuit, when the switch does not press the correct external force, four pins is not connected, the circuit is disconnected state.

2. Metal key switch principle classification:

Metal key light switch according to its principle can be divided into two types. One is to use conductive rubber to complete the switching state of the switch. The switch feels good, but the contact resistance is large, about 10000 of the previous model. The other is to use metal shrapnel to complete the switch state. The metal button switch feels nice. When the key is pressed to a certain point, a clicking sound will appear
