Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.
