Technical Field

The invention relates to elevator equipment, in particular to a plug-in contact switch, a socket assembly and an elevator.

background

in elevators, a plug-in door contact switch is commonly used to control the opening and closing of an elevator door or to control the stopping and starting of an elevator at various floors. After the electric plug of the door contact switch is connected with the contact of the spring piece in the socket, the elevator control system controls the elevator to be started, and when the door electric shock switch is disconnected, the elevator control system controls the elevator to stop at the corresponding position.
