A limit switch is provided with a switch body having a contract mechanism inside, and an operation unit connected to the switch body. The operation unit may include a pivoting shaft support that permits pivoting of the pivoting shaft with respect to the housing body in a state of an external force along the extending direction of the pivoting shaft being not applied to the operation lever, and contacts the peripheral wall to support the pivoting shaft in a state of an external force along the extending direction of the pivoting shaft being applied to the operation lever.

A switch includes a base, a fixed contact member having fixed contact, and a movable contact member having a movable contact. The movable contact member moves in a first direction to bring the movable contact into contact with the fixed contact, and moves in a second direction opposite to the first direction to separate the movable contact from the fixed contact. The switch further includes a cover, an elastic body that energizes the movable contact member in the second direction, and an operation body configured to move the movable contact member sequentially to a first position, a second position, and a third position.

A paddle switch system comprises a housing, a paddle having a pivot member pivotally disposed in the housing for operating an electrical switch within the housing in response to a force on the paddle, a cover coupled to the housing wherein the housing and the cover partially enclose the paddle, and a vibration reduction mechanism disposed in the housing proximate the pivot member of the paddle. The electrical switch comprises a dome switch and the paddle is disposed in the housing to partially preload the dome switch.

A limit switch operating head includes a shaft rotatable in clockwise and counter- clockwise directions, a cam member supported on the shaft and that is rotatable in the clockwise and counter-clockwise directions responsive to rotation of the shaft, and a follower actuated by the cam member responsive to rotation thereof, with the follower including a pivot pin, a lever portion pivotable about the pivot pin, and a rolling pin mounted to the lever portion and in contact with the cam member. An actuator member contacts the lever portion and translates linearly in a first direction or second direction responsive to pivoting thereof. The rolling pin moves along a profile of the cam member upon rotation of the cam member so as to cause the lever portion to pivot, with the actuator member linearly translating in the first direction or the second direction responsive to the pivoting of the lever portion.

A switch is provided with: a base; a fixed contact member that has a fixed contact; a movable contact member that has a movable contact, moves in a first direction to bring the movable contact into contact with the fixed contact, and moves in a second direction opposite to the first direction to separate the movable contact from the fixed contact; an elastic body that energizes the movable contact member in the second direction; and a cover that covers the fixed contact member and the movable contact member. An operation body is configured to move the movable contact member sequentially to a first position to which the movable contact member is moved from an initial position in the first direction to bring the contacts into contact with each other, a second position to which the movable contact member is moved from the first position in the second direction while the contacts are kept in contact, and a third position at which the movable contact member is moved again in the first direction from the second position, the third position located between the first position and the second position.

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.

A safety switch (2) with a latching unit (12), by means of which an associated actuator (3) is held in a latched position. The latching unit (12) has an arrangement of latching jaws (14). Each latching jaw (14) is spring-mounted by means of a spring unit (15). The latching jaws (14) are concentrically arranged and each face one another with a first free end and delimit an insertion opening (A). The latching jaws (14) are held in latched position by the spring forces generated by the spring units (15). The latching jaws (14) can be displaced against the spring forces of the spring unit (15), which serves to enlarge the insertion opening (A).
