A button switch is a simple and widely used main control device that uses a button to push the transmission mechanism, causing the moving and stationary contacts to switch on or off and achieve circuit switching. In electrical automatic control circuits, it is used to manually issue control signals to control contactors, relays, electromagnetic starters, etc.
A button switch, also known as a control button (abbreviated as a button), is a low-voltage electrical device that can be manually reset and generally automatically reset. Buttons are usually used in circuits to issue start or stop commands to control the connection and disconnection of coil currents in electrical devices such as electromagnetic starters, contactors, relays, etc.
A button switch is an electrical device that operates when pressed and resets when released. It is used to connect and disconnect small current circuits. Generally used in control circuits with AC/DC voltage below 440V and current less than 5A, it is not directly operated in the main circuit and can also be used in interconnected circuits.
In practical use, in order to prevent misoperation, different markings or colors are usually made on the buttons to distinguish them, including red, yellow, blue, white, black, green, etc. Generally, red indicates operations in situations of "stop" or "danger"; Green indicates' start 'or' connect '. The emergency stop button must be a red mushroom-shaped button. The button must have a metal protective retaining ring, and the retaining ring should be higher than the button cap.
