Bistable Door Control Switch for Lift Systems

The Elevator bistable switch mkg131-03 is a door-related control part used in many lift models. A bistable switch stays in one set position until it is shifted to the other, which makes it useful for steady door commands without the need for constant pressure. In elevator systems, this type of switch helps manage door signals in a stable way, supporting clear open and close instructions during normal use or service checks. It also plays a role in keeping the door circuit steady so the lift panel receives the correct input during operation.

This switch is placed inside the lift control area or near the door mechanism, depending on the design. Its simple action and fixed positions help reduce faults and give maintenance teams a clear point of control when checking door behaviour or adjusting related components.
