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 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.

Switch

A fixing component for a switch including a flange, a ring attachment, and a screw attachment, the flange including a projection provided on an outer peripheral surface, the screw attachment including, on an inner peripheral surface, an insertion area into which the projection of the flange is inserted, a projection engaging part into which the projection of the flange is fitted, and an interference projection which is formed between the projection engaging part and the insertion area and has a smaller inner diameter than diameters of the projection engaging part and the insertion area, the projection of the flange including a first projecting portion and a second projecting portion where the first projecting portion is fitted into a guiding groove, and the second projecting portion is configured to traverse the interference projection to be fitted into a fitting groove when the flange and the screw attachment are rotated relatively.

Push-button switch, selector switch, and fixing component therefor

A limit switch has a housing having an opening in a front surface of the housing, and a connection hole in which a lead wire is drawn made in a bottom surface of the housing, a switch main body fixed in the housing, a front surface of which is vertically partitioned into a plurality of stages, a pair of fixed contact terminals embedded at each of the stages, an operation shaft exposed from a ceiling surface of the switch main body, a contact that is opened and closed by driving the operation shaft in a shaft center direction, and a projection provided between the fixed contact terminals embedded at the stages of the front surface of the switch main body.

Limit switch

Push button switch

An operation switch where a switch unit can be separated from an operation unit in a simple manner even when the operation switches are densely fitted is disclosed herein. The operation switch of the invention includes an operation unit that is disposed on a front surface side of a panel and operated by external pressing force, a switch unit that can be separated from a rear surface side of the panel from the operation unit, a latching unit formed on an external circumferential surface of the operation unit along an axial center direction, a latching receiving unit which is formed along an external circumferential surface of the switch unit and to which the latching unit is latched, and a release lever that releases a latching state of the latching unit and the latching receiving unit so that the switch unit is separated from the operation unit.

Operation switch

Switch module for limit switch

A switch includes a switching mechanism, an operating mechanism with a key which normally causes the switching mechanism to be in a switched-off condition when it is pulled out and to be displaced against a biasing force to be in a switched-on condition when the key is inserted, and a locking mechanism for maintaining the switching mechanism locked in the switched-on condition and releasing it from the locked condition if a load greater than a specified magnitude is applied to the key while the switching mechanism is locked such that the switching mechanism is set back in the switched-off condition. The switching mechanism may be contained in a head case attached to a main case containing the operating mechanism. The main case also includes a forcing mechanism which tends to force the switching mechanism in the switched-off condition. Normally when the head case is attached to the main case, the forcing mechanism is released from its forcing function but when the head case is removed from the main case, the forcing mechanism functions to displace the switching mechanism into the switched-off condition.

Door switches

A switch structure suitable for a compact switch device is disclosed. The switch structure is formed of a push button, a switch body switched in correspondence with a pressing operation of the push body and a switch base or a switch holder holding these elements unitary, and a spring member which is elastically deformed in correspondance with the pressing operation of the push button is provided between the push button and the switch body. The switch holder has a fixing member detachably engaged with the switch body for fixing the switch body. The spring member provided between the push button and the switch body makes the pressing stroke longer by the amount of elastic deformation of the spring member. A fixing member provided in the holder fixes surely and easily the switch body in the holder.

Compact switch device having a push button with long stroke

This invention provides a pushbutton switch which produces a click sound, the loudness of which is easily variable. In response to the vertical movement of operating cams of a pushbutton, a plate spring moves up and down. The moment when the edge of the operating cams trips over click spring portions of the plate spring, a force is applied to the plate spring so that the plate spring hits the inner top wall or bottom wall of a housing. In this manner, the pushbutton switch provides both a snap feeling and a click sound.
