A pressure receiving member which has a diaphragm held in a pressure receiving case is manufactured independently of a main sensor body member, which has a switch accommodated in a switch case. The pressure receiving member and the main sensor body member are then assembled to provide a pressure sensor. According to the present invention, since the pressure receiving portion and the main sensor body are manufactured individually, a diaphragm movement test can be carried out individually of the testing of switch turning on and off, and hence only a satisfactory pressure receiving portion and a main sensor body which passed the respective tests will be utilized in the operation of assembling pressure sensors.

Method of manufacturing fluid pressure sensor

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 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.

A pressure receiving member which has a diaphragm held in a pressure receiving case is manufactured independently of a main sensor body member, which has a switch accommodated in a switch case. The pressure receiving member and the main sensor body member are then assembled to provide a pressure sensor. According to the present invention, since the pressure receiving portion and the main sensor body are manufactured individually, a diaphragm inversion movement test can be carried out individually of the testing of switch turning on and off, and hence only satisfactory pressure receiving portion and main sensor body which passed the respective tests will be utilized in the operation of assembling pressure sensors.

Plunger type fluid pressure switch

This slide switch includes: a casing formed in a hollow box shape with an open top; several fixed contacts on the bottom surface of the casing and several terminals connected to them extending to the outside of the casing; a cover mounted to close the open top of the casing, formed with a hole opposed to the fixed contacts; and a slide member disposed inside the casing, which has a control portion protruding out through the hole in the cover and a movable contact portion made of a resilient electrically conducting material which bears against the internal bottom surface of the casing and thereby produces a biasing force on the slide member to impel it in the direction towards the cover. The movable contact portion of the slide member, according as the control portion of the slide member is moved from outside the casing, selectively connects together a combination of the fixed contacts. The movable contact is mounted to the slider so that movement of the contact within a plane parallel to the bottom surface of the casing is solely restricted to the sliding direction of the slider.

Push-button switch with plunger and switch mechanism

A slide switch has a switch operating member at its upper surface which is slid back and forth for operating the slide switch. An adapter is provided for operating this slide switch from the side, and has a main body which has a base and clamp members extending from opposite sides of the base to define a space between them, the clamp members being adapted to grip the slide switch between them so as to secure the adapter on the top of the slide switch with the slide switch being held at least partly in the space between the clamp members. The adapter has an actuator pivotally fixed to the main body, and this actuator has a lever portion which protrudes out from the main body to the side and an actuation portion which, with the slide switch held between the clamp members, engages with the switch operating member of the slide switch, so as to slide it as the actuator is pivoted with respect to the main body. As a result, the slide switch, which ordinarily is for operation from its top, can be converted to be operated from its side.

This slide switch includes: a casing formed in a hollow box shape with an open top; several fixed contacts on the bottom surface of the casing and several terminals connected to them extending to the outside of the casing; a cover mounted to close the open top of the casing, formed with a hole opposed to the fixed contacts; a slide member disposed inside the casing, which has a control portion protruding out through the hole in the cover and a movable contact portion made of a resilient electrically conducting material which bears against the internal bottom surface of the casing and thereby produces a biasing force on the slide member to impel it in the direction towards the cover; and a seal member interposed between the inside of the cover and the side of the slide member facing it, the seal member being squeezed between the slide member and the cover, a seal between the inside of the casing and the outside thereby being produced. The movable contact portion of the slide member, according as the control portion of the slide member is moved from outside the casing, selectively connects together a combination of the fixed contacts. By this seal member being provided, a good sealing performance for the switch is available, and therefore, when the switch is soldered to a printed circuit board and a cleansing fluid is thereafter used for cleansing off solder residue, no contamination is introduced into the slide switch.

Sealed slide switch

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.
