Claims

[Scope of utility model registration request]

A movable control arm has a contact on one end that contacts a power supply terminal connected to the main circuit, and is rotatably provided on the other end; a catch body whose side is hooked to the hook body and which rotates when the hook is released from the hook body when shutting off; one end is rotatably provided to the catch body, and the other end is the movable control arm. first and second link bodies which are rotatably provided to each other and which separate the movable control arm from the power supply terminal in conjunction with the rotation of the catch body at the time of shutoff; a first pin rotatably supporting one end of the catch body, and a second pin provided parallel to the first pin; A stopper body for restraining movement of the first link body when the circuit is disconnected.
