The working principle of the push button switch and instructions for use

2021-11-10

A push button is a control switch that uses a certain part of the human body (usually a finger or palm) to apply force and has a spring stored energy to reset. It is one of the most commonly used master electrical appliances. The allowable current through the contact of the button is small, generally not more than 5A. Therefore, under normal circumstances, it does not directly control the on and off of the main circuit (large current circuit), but sends command signals in the control circuit (small current circuit) to control electrical appliances such as contactors and relays, and then they control the main circuit. On-off, function conversion or electrical interlocking.

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. The push button must have a metal protective retaining ring, and the retaining ring should be higher than the button cap to prevent accidental activation of the button and cause malfunction. The material of the button board and push button box where the button is installed must be metal and connected to the main ground bus of the machine.
