Construction Elevator Limit Switch
Limit switch, also known as stroke switch, can be installed on relatively static objects (such as hoist mast, elevator car doorframe, etc.) or moving objects (such as building lifts cage, etc.). When the moving object approach the static object, the rod driven contact of the switch's connecting causes the circuit to break or close. The circuit and the motor of construction elevator are controlled by the change of the switching state of the switch contacts.
