Spring Return Push Button Switch New Design Emergency Spherical Mushroom Head

Push button switch, also known as control button (push button), is a low-voltage electrical appliance that can be manually and generally reset automatically. Buttons are usually used in circuits to issue start or stop instructions to control the on and off of electrical coil currents such as electromagnetic starters, contactors, and relays.

The push button switch is an electrical appliance that is used to switch on and off small current circuits that is pressed to act, and released to reset. It is generally used in control circuits with AC and DC voltages below 440V and currents less than 5A. Generally, the main circuit is not directly manipulated, and it can also be used in interconnecting circuits.

In actual use, in order to prevent misoperation, buttons are usually marked or painted in different colors to distinguish them. The colors are red, yellow, blue, white, black, green, etc. Generally, red means “stop” or “dangerous” operation; green means “start” or “on”. The emergency stop button must be a nred mushroom button. The button must have a metal protective retaining ring, and the retaining ring should be higher than the button cap to prevent accidental operation of the button. The material of the button board and button box where the button is installed must be metal and connected to the main ground bus of the machine.
