A push-button switch including a switch base which is formed into two divisions each for mounting a switch mechanism thereon, the terminals of one circuit provided within the switch mechanism being molded in insertion in the respective division switch base, whereby the switch base is made smaller in size and simplified in assembly of the push-button switch.

Push-button switch

The push-button switch according to the present invention comprises a switch base, a plunger movable along a sliding portion thereof, an alternate cam pivotally provided with said plunger and guides for said alternate cam integrally formed with said sliding portion of said plunger. Therefore, the guides for the alternate cam are positioned with high accuracy with respect to the sliding portion achieving secured movement of the alternate cam.

A switch in which a switch unit is constituted by situating the free end of a first movable member disposed with a contact between stationary contacts opposing to each other along the vertical direction, while engaging the other end of the movable member to a fixed portion, pivoting one end of a second movable member to the free end of the first movable member while engaging a spring to the other end of the s econd movable member, thereby biasing the contact of the first movable member to one of the stationary contacts, and setting the other end of the second movable member to a switch operation portion, as well as a switch wherein a housing, which enhouses a push button unit containing an illumination unit, a socket unit to be connected to the illumination unit and a plunger to be connected to the push button switch, contains to secure the switch mechanism at the lower opening thereof and the lower end of the plunger is disposed to the switch operation portion.

A push-button switch having a lamp portion and a switch portion. The lamp portion includes a lamp, a lamp holder, a lamp casing, and a housing. The lamp holder is fixed within the housing and the lamp casing moves up or down to turn off or turn on the switch. The switch portion of the push-button switch includes a switch base, a plunger, and a cam. The plunger moves in conjunction with the lamp casing and has a cam formed on one end. The cam is guided along guides that are formed on the switch base, and holds the lamp casing and plunger in a raised position in which the switch is turned off and a lowered position in which the switch is turned off.

Push-button switch with plunger and switching mechanism

A push-button switch for turning on and off of a switch mechanism accommodated at one side in a housing through a plunger accommodated at the other side in the housing and moved in association with the pressure application thereto, wherein a partition wall is formed between said plunger and said switch mechanism so as to divide the interior of said housing into a plunger chamber and a switch mechanism chamber.

Push-button switch with plunger and switch mechanism

A switch comprising a cylindrical housing, an actuator mechanism disposed at one end of the housing for contacting an object to be sensed by the switch, a plunger slidably housed within the housing for receiving a displacement by the actuator mechanism, and a switching mechanism associated with the plunger for switching a circuit in accordance with the actuation by the plunger. The actuator mechanism includes a conical supporting member tiltably engaged with a flange member formed in the aforesaid one end of the housing.

Plunger sensing switch

An illuminated display assembly comprising a light emitting member, a socket base member, a cap member housing the light emitting member therewithin and including at least one engaging leg to be engaged with the socket base member, and connection means carried by the socket base member for disengageably contacting a connection terminal of the light emitting member, the light emitting member being removably supported within the case member.

Illuminated display assembly

An improved push-button switch which is so arranged that generation of heat at a journalled portion of a movable piece is eliminated by forming contacts of the movable piece into double-break contacts so that no current flows through the journalled portion, while a sufficient contact gap is available even when the push-button switch is made into a compact size.
