The emergency push button control switch has a simple structure of 1NC/ 1NO+1NC/ 2NC+1NO/ 2NO+1NC contact form, sensitive response and long service life. The push button switch box is widely used in electrical automatic control circuits. And mainly used to manually send control signals to control contactors, relays, electromagnetic starters, etc.

Tips: selection of NO and NC contact form for Emergency push button Switch
The most basic function of the emergency stop button is to stop in an emergency to avoid mechanical accidents or personal accidents. However, due to the long-term operation of the machine, the line, especially the emergency stop line part, may cause a fault and open circuit. At this time, if the emergency stop button uses a normally open contact, the line fault of the emergency stop part will not be found. If the emergency stop button is used then it will be too late. When using normally closed contacts, when the emergency stop part of the circuit fails, it will at most cause the machine to stop, and the loss will be relatively small. When designing an electrical control system, it is best to use a normally closed contact for the emergency stop button, so that the safety factor is relatively high.
