Claim 0:
1. An elevator apparatus comprising:
a safety gear disposed at a car;
an electric actuator for operating the safety gear; and
a brake state detection switch fixed to the car for detecting a brake state of the safety gear,
wherein the brake state detection switch is operated by a mechanism which operates the safety gear with an operation of the electric actuator,
wherein upon interruption of a power supply of the car, the electric actuator operates the safety gear thereby displacing the mechanism to a first position toward the brake state detection switch, the brake state detection switch remaining off while the moving mechanism is in the first position, and
wherein upon braking of the safety gear thereby displacing the mechanism to a second position in contact with the brake state detection switch, the brake state detection switch is turned on.
