The PB-EXIT control button can be used for momentary release of fail-safe or fail-secure electric locks and widely used in door, gate, exit, automation control, etc. It may also be used to input an exit signal to the access control system. It is a spring-loaded, square green exit button mounted on a stainless steel plate. The SPDT contacts switch when the button is depressed and return when released. In some areas, local building or fire safety regulations may limit the use of exit buttons and it is recommended to consult or get approval prior to installing exit buttons.
