A switch device includes an actuation unit, a movable unit, a first base, and a second spring, which is a torsion coil spring that acts between the actuation unit and the movable unit. The movable unit is movable with respect to the base. The second spring applies a force to the actuation unit when the actuation unit is at a third position in a direction that is not parallel to a direction in which the torsion coil spring applies a force to the actuation unit when the actuation unit is at a fourth position.

Provided is an electric switch, including a casing, an actuator, a movable contact frame, a snap-action resilient member, a lock mechanism, a signal switch and a contact switch. The actuator is capable of reciprocating along a first direction. The movable contact frame is provided with a retaining portion. The snap-action resilient member is arranged in the movable contact frame and is compressed by the actuator when the actuator moves. The lock mechanism includes two lock members which are capable of reciprocating in the mounting cavity along a second direction with the movement of the actuator, so as to lock or unlock the retaining portion. A brush of the electric switch is arranged on the movable contact frame. A movable contact of the contact switch is arranged on the movable contact frame.

A switchgear includes a movable part capable of reciprocating movement in first and second directions, a movable contact coupled to the movable part and capable of reciprocating movement relative to the movable part, a biasing member that biases the movable contact, a latch part capable of switching between a first state in which movement of the movable contact in the first direction is restricted and a second state in which movement of the movable contact in the first direction is permitted, and a fixed contact provided on a side of the first direction with respect to the movable contact. When the movable part and the movable contact move in the first direction, after movement for a predetermined distance, the movement of the movable contact is restricted by the latch part in the first state, and then, when the movable part has moved further in the first direction, the latch part is switched to the second state.
