Metal push button switch Structure

The push button switch generally consists of a button cap, a return spring, a bridge-type moving contact, a static contact, a pillar connecting rod and a shell. There is an electromagnet adsorption device inside the button. When the button is pressed down, the electromagnet is energized to generate magnetism, and the circuit is connected or disconnected by the adsorption device to realize functions such as remote control circuit.

According to the opening and closing state of the contacts when the push button switch is not subjected to external force, it is divided into start push button switch (normally open button), stop push button switch (normally closed button) and composite push button switch (NO and NC contact combination buttons). The contact of the start push button switch is closed when the button cap is pressed, and the contact is automatically disconnected and reset when released. When the stop push button switch is pressed down on the button cap, the contacts are separated, and the contacts are automatically closed and reset when released. When the composite push button switch presses the button cap, the bridge-type moving contact moves downwards, the NC contact is opened first, and then the NO contact is closed. When the button cap is released, the NO contact is first broken and reset, and then the NC contact is closed and reset.

Except 1NO1NC, our factory can also combine NO and NC arbitrarily. Such as 2NO,2NC and so on. Our factory has very professional engineers to help you customize metal push button switch. Besides,For reliability and safety, our factory switches are rated for current and voltage. This is necessary since higher voltage or current requirements call for larger, more expensive parts, and switches, like most parts, are only as large as necessary. Cell phones and portable radios have small requirements; industrial machines have large requirements. We are not afraid of any difficulties, as long as you need, you can contact us.
