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.

Limit switch

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.

Wireless switch

A limit switch may be provided with a switch body having a contact mechanism inside, and an operation unit connected to the switch body. The operation unit comprises an elastic part that energizes the operation lever from the first motion position towards the return position via the pivoting shaft and the first cam, and energizes the operation lever from the second motion position toward the return position via the pivoting shaft and the second cam, a first cam's pivoting restriction part that restricts the pivoting of the first cam in a first direction in which the operation lever moves from the return position to the second motion position, and a second cam's pivoting restriction part that restricts the pivoting to the second cam in a second direction in which die operation lever moves from the return position to the first motion position.

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.

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 wireless switch includes a cover member, a button member, a first plunger, a second plunger, a trigger spring, a return spring, a shaft, a housing, and a power generation module. An intermediate member constituted of the first plunger, the second plunger, the trigger spring, the return spring, and the shaft is connected between the button member and the power generation module. The intermediate member prevents a position of the shaft making contact with the power generating shaft of the power generation module from changing, and causes stress to build up in the trigger spring, until a movement distance of the button member reaches a predetermined distance. The intermediate member releases the stress built up in the trigger spring and pushes the power generation shaft with the shaft using the released stress upon the movement distance of the button member reaching the predetermined distance.

Power generation apparatus and wireless switch

Box cover for limit switch

A wireless switch includes a button member, a power generation module, an RF module, and a notification unit. The button member is mounted in a housing, and is configured to move. The power generation module is configured to generate power using energy produced by the movement of the button member. The RF module is connected to the power generation module, and is configured to transmit a switch signal using power generated by the power generation module. The notification unit is configured to operate using power generated by the power generation module. The RF module controls the notification unit in one or more notification states according to a strength or details of a reception state signal corresponding to the transmitted switch signal.

A limit switch having a housing having a box, an attachment hold made in a side surface of the box, having a cylindrical bearing section, a rotating shaft rotatably inserted through the cylindrical bearing section, a cam unit provided in a leading end portion of the rotating shaft, and an operation lever provided in the other end portion of the rotating shaft. Rotational action of the operation lever is converted into vertical action by the cam unit in the box. A contact of a switch main body accommodated in and fixed to the housing is opened and closed. An outer diameter of the cam unit is smaller than an inner diameter of the attachment hole.

Limit switch and method for producing same

A limit switch is provided that is returned to an original position even if a turning angle of a turning lever becomes 90 degrees. In a section perpendicular to a turning shaft, a cam is formed such that a whole contact surface of the cam with a cam receiver is located on a side of the cam receiver with respect to a shaft center of the turning shaft when the external force does not act on the turning lever.

A limit switch includes fixed contacts and a movable contact, the fixed contacts and the movable contact formed from an Au&#x2014;Ni metal alloy of no less than 97% Au by weight. The limit switch detects position, change, movement, number of passes, or the like and outputs an 'on' signal or an 'off' signal depending on whether a detection occurred.

A power-generating module has a base, a power-generating unit that is placed in the base, a plunger that is placed in the base and that vertically reciprocates, and a drive section that interlocks with the reciprocation of the plunger and starts up the power-generating unit. The drive section is biased to a boost-up position where the plunger is boosted up. The drive section has at least two links that turn between the boost-up position and a press-in position where the power-generating unit is started up. Both ends of one of the links are turnably supported by the base. Both ends of another link are turnably supported by the plunger. The links turn in an interlocking manner by coupling to each other.

Power-generating module

A switch has a rotary shaft that rotates in response to an external force, a cam provided on the rotary shaft and including a cam action section, wherein the cam rotates in response to the rotation of the rotary shaft, a displacement member including a cam support section that contacts the cam action section, wherein the displacement member is displaced in response to the cam support section being pressed by the cam action section rotating, and a switch module that performs an on-off action in response to the displacement of the displacement member. The cam action section is made of a metal. The cam support section is made of a resin softer than the cam action section.
