Abstract: A small switch comprises a casing, a plurality of optical fibers attached to the casing, a vertically movable member disposed, facing the ends of the optical fibers. The movable member has a resilient member provided at one end, and a member, which is deformed to be contracted by supplying an electric power, provided at the other end. The member, which is deformed to be contracted, that is, for causing the movable member to move vertically may comprise a shape memory alloy or a bimetal. The movable member may comprise an interceping plate has an aperture for transmitting therethrough, or a prism for deflecting a light beam.

Abstract: A printed wiring board is mounted with an electronic component which is provided with grooves at the opposite sides thereof. The grooves are constructed so that the electronic component can be mounted on the printed wiring board in either the vertical or horizontal directions. Preferably, the grooves have a cross-shaped configuration, one extending vertically and one extending horizontally. The grooves may be formed on tongue pieces projecting from the electronic component body. The groove may be provided with a resilient piece. Another groove may be provided on the body so as to be capable of changing the direction of terminals.

Abstract: A control instrument which is mounted in a recess on a printed wiring board is disclosed. The control instrument includes terminals, provided at a bottom surface and offset from a central plane, which engage pattern portions formed at a bottom section of the recess. A resilient member is provided over a top portion the control instrument. Leg members of the resilient member extend over opposite side walls the control instrument. The leg members project outward at a central portion and have apertures formed therein. The control instrument can also have longitudinal grooves over which the leg members extend.

Abstract: A miniature push-button switch having and improved switch body wherein a plurality of fixed contacts are each formed by bending an electrically conductive plate material to have one end acting as a contact portion, for contacting a movable contact which is adapted to slide in the longitudinal direction of the switch, and the other end acting as a switch terminal. The switch terminals are arranged in order along the direction substantially perpendicular to the longitudinal direction of the switch and comprise a normally open, NO, switch terminal, a common, C, switch terminal and a normally closed, NC, switch terminal interposed between the NO switch terminal and the C switch terminal.

Abstract: A rectangular switch body has a plurality of terminals of round flexible wire rods and is provided at its four outer side surfaces with engagement members. Various kinds of cross-sectionally C-shaped brackets of a resilient metal plate provided with engagement members are prepared. An insert mount having a mount frame with at least three side walls engageable with at least three side surfaces of the switch body and engagement members is prepared. By using one of the brackets or the insert mount, the switch body is mounted on a printing wiring board in a desired direction or on a panel.

Abstract: A small-sized rotary switch which comprises a switch base plate, fixed contacts formed on the base plate, a movable contact selectively engageable with one of the fixed contacts, a converter for holding the movable contact, a rotary shaft for rotating the converter, a cap adapted to accommodate all of the above-mentioned members therein and provided at the upper portion thereof with an aperture through which the rotary shaft extends, a stopper plate attached to the rotary shaft and disposed on the upper portion of the cap, the stopper plate being provided with an ear piece, and a variable stopper attached to the upper portion of the cap, with the stopper plate intervening therebetween, with an engagement projection being formed on either one of the cap and the variable stopper to engage the ear piece of the stopper plate.

Abstract: Disclosed herein is a small-sized push-button switch in which a switching operation is made by depressing a push-button to cause a plunger provided at the lower portion of the push-button to move vertically. The switch mechanism provided within the switch comprises a switch base, an upwardly extending arm having its fulcrum on the switch base and being swung about the fulcrum by the plunger, fixed contacts and movable contacts longitudinally or axially provided on the switch base, and a resilient piece bridged between the other end of the arm and the movable end of the movable contact. At least one switch mechanism is inserted into and mounted on a switch body through a switch auxiliary base. The switch mechanism is disposed relative to the plunger so that the operating direction of the plunger is located at right angles to the switch operating directions of the movable contact relative to the fixed contacts.

Abstract: A photo-switch having a switch case, a plurality of photo-transmissive bodies inserted into the switch case with their ends arranged in a side-by-side relation, and an intermediate photo-transmissive body or a reflecting member carried by a switching means. The switching means is operable to move the ends of the intermediate photo-transmissive body or the reflecting member into and out of optical connection with the ends of the plurality of photo-transmissive bodies thereby to selectively interrupt the transmission of light between the photo-transmissive bodies. When the intermediate photo-transmissive body or the reflecting member is moved away from the ends of the photo-transmissive bodies, a light shielding member is brought into the gap therebetween to improve the resolution of the photo-switching operation.

Abstract: Disclosed herein is a mounting frame equipped with a decorative plate, for mounting a switch or the like. The mounting frame includes a decorative plate having a through-hole formed thereon so as to mate with a sleeve which is step-wise formed at the upper portion of a switch, a pilot lamp or the like, and leg portions vertically suspended from the lower end portions on both sides of the decorative plate. When the sleeve is fitted into the through-hole while the inner side surfaces of the leg portions or a bridge interconnecting the lower portions of both leg portions are anchored to the corresponding outer side surfaces of the switch, the pilot lamp or the like, the switch, the pilot lamp or the like can be mounted to, and dismounted from, the mounting frame in one-touch operation.

Abstract: Disclosed is an illumination-type pushbutton switch construction including an operation section slidably arranged in a switch housing and a switch operating section for actuating a switch section in cooperation with the operation section, wherein the operation section and the switch operating section are improved. The improved operation section includes a pushbutton, a switch actuating member detachably fitted with respect to the pushbutton and a supporting frame detachably attached to the switch actuating member, the supporting frame having a holding portion for holding a light emitting element. The improved switch operating section includes an actuating plate disposed so as to be slidable along the inner surface of the switch housing, the actuating plate being detachably attached to the switch actuating member, to thereby allow the pushbutton, switch actuating member, supporting frame and actuating plate to be connected in series and detachable from one another so as to be integrally movable.
