Wireless switch

A wireless switch, comprising:

• a switch body;
• a push button connected to the switch body in a state of being movable along an approaching/separating direction that the push button is closer to and away from the switch body, between a non-operating position away from the switch body and an operating position closer to the switch body than the non-operating position;
• a signal output device accommodated in the switch body and configured to output a switch signal in response to a movement of the push button from the non-operating position to the operating position;
• and
• a restriction member that restricts the movement of the push button from the non-operating position to the operating position when the push button is located at the non-operating position, wherein
• the restriction member is configured to be movable between a restriction position and a release position along an operating direction intersecting the approaching/separating direction when the push button is located at the non-operating position, the restriction position being a position that the restriction member is disposed between the switch body and the push button in the approaching/separating direction and a restriction on the movement of the push button from the non-operating position to the operating position is imposed, and the release position being a position that the restriction is released,
• the restriction member includes:
• a main body unit disposed to be movable along the operating direction between the restriction position and the release position;
• and
• an operation unit connected to the main body unit, the operation unit being capable of moving the main body unit from the restriction position to the release position by a movement of the operation unit in the operating direction,
• the wireless switch comprises a cover member surrounding the push button in the approaching/separating direction,
• the main body unit extends in the operating direction along an inner surface of the cover member, the inner surface opposing the push button,
• the cover member includes a guide unit on the inner surface opposing the push button, the guide unit being configured as a groove to accommodate the main body unit and guide the movement of the main body unit in the operating direction,
• the wireless switch further comprises
• a biasing member that biases the main body unit from the release position toward the restriction position,
• the main body unit has substantially annular shape, and
• the biasing member is arranged on an opposite side of the operation unit with respect to a center of the restriction member when viewed from the approaching/separating direction.
