Abstract: A wireless switch includes a switch body, a push button connected to the switch body in a state of being movable along an approaching/separating direction between a non-operating position and an 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 operation position when the push button is located at the non-operating position.

Abstract: A limit switch includes: a switch main body capable of being switched on and off; and an operation unit connected to the switch main body. The operation unit includes: a housing having a box shape; a shaft portion including a shaft main body and a cam portion the shaft main body being supported by the housing in a state of being rotatable forward from a return position toward a first operation position around a rotation axis extending in the first direction and being rotatable backward from the return position toward a second operation position opposite to the first operation position with respect to the return position, the cam portion being provided in the shaft main body located inside the housing and being configured to rotate forward and backward together with the shaft main body; a biasing portion configured to return the shaft main body to the return position; and a plunger configured to move in the second direction by rotation of the cam portion to switch on and off of the switch main body, and configured to be able to set an operation mode from either one-side operation or both-side operation.

Abstract: A limit switch includes: a switch main body; and an operation unit connected to the switch main body. The operation unit includes: a housing; a shaft member, a biasing member; and a plunger. The shaft member includes a shaft body supported by the housing in a manner rotatable from a return position to an operation position around a rotation axis, and a cam. The plunger includes: a plunger body; and at least one contact portion. The at least one contact portion includes a recess positioned on a facing surface facing the at least one protrusion and recessed in a direction moving closer to the switch main body. The recess includes: a first end; a second end; and an inclined surface. The inclined surface is inclined in a direction moving closer to the switch main body as the inclined surface extends from the second end to the first end.

Abstract: A limit switch is provided with a switch body having a contact mechanism inside, and an operation unit detachably connected to the switch body. The operation unit may include a pivoting shaft and a bearing. One of the pivoting shaft and the bearing includes a protrusion that extends in a radial direction with respect to the pivoting shaft. The other of the pivoting shaft and the hearing includes a pivoting restriction part that is disposed around the pivoting shaft so as to be able to contact the protrusion, and restricts pivoting of the protrusion around the pivoting shaft.
