Abstract: The keytop of a push-button switch includes a keytop portion situated on the top of a resin film, and a retaining portion situated on the underside of the resin film. The keytop portion and retaining portion are formed into a unitary body by a resin-molding process in which resin is passed through a hole provided in the resin film such that the resin film is sandwiched between the keytop portion and the retaining portion. In another embodiment, the retaining portion is loop-shaped and is formed into a unitary body with the keytop portion by a resin-molding process in which the resin passes through a plurality of holes provided in the resin film in a pattern corresponding to the loop-shaped circumference of the retaining portion. The resin film is sandwiched in a water-tight state between the keytop portion and the loop-shaped retaining portion.

Abstract: An environmentally controlled portable toilet designed to neutralize and confine contaminating agents such as bacteria, odors, vapors and other airborne particles inside the bowl by generating and maintaining a cyclone-type air circulation inside the bowl-structure. A circular shaped bowl-structure (170) with a circular air-trapping cavity created inside the bowl-structure (170) by a seat-skirt (188), confines the contaminating agents during toilet use and improves the efficiency of the air circulation. A removable air-cooling tray 134, and sanitizer and odor conditioner cartridges (131) are employed to cool the air moving inside the air-trapping cavity, and respectively, to neutralize the contaminating agents by releasing sanitizing and odor conditioning agents into the air flow circulated inside the bowl (170). A toilet seat (182) having an ergonomic design has a seat-skirt (188). The invention is applicable to portable toilet systems including children's training toilets.

Abstract: A support assembly for supporting two poppel-type actuation switches at a housing, such as a radiotelephone handset housing. The actuation switches are positioned beneath a support body of the support assembly and maintained in a desired orientation relative to such support body by pawl arms which extend beneath the support body. Post members extend beneath the support body to abut against membranes of the respective actuation switches. The support body is affixed to the housing by way of retaining arms positioned to extend beneath the support body midway along the length thereof while permitting limited pivotal movement about rocker arms positioned at sides of the support body responsive to twisting moments applied to the support body. The twisting moments applied to the support body are transmitted to the poppel-type switches by way of the post members form the actuation forces to actuate the poppel-type switches supported thereat.

Abstract: An on-line switch includes a switch housing formed by combining an upper half shell on a lower half shell, a push-button switching device encased in the housing having a push button reciprocatively held in a button holder of the switching device and normally protruding upwardly outwardly beyond the housing for depressibly switching on or off of a power supply through the on-line switch connected between an input cord and an output cord of a power source, an electrically insulative protective cover integrally formed on an outer circumferential surface of the switch housing for completely shielding the switch housing for water proof and for protecting the cords from their damage, and a sealing cap formed as a telescopic bellows and made of electrically insulative elastomer material secured with the button holder of the push-button switching device for sealing the push button held in the switching device in the switch housing for water proof purpose, thereby providing an on-line switch of a power line suitable f

Abstract: An arm switch assembly, for an electrical instrument having a casing and electrical contacts, comprises an elongated insulating body member with a conductive member moved into engagement with and disengagement from the electrical contacts in response to operation of a camming mechanism. The camming mechanism is slidably mounted to the casing and has a cam surface movable between first and second positions. The insulating body member includes first and second ends, and a lateral arm connected to the first end permits the insulating body member to pivot relative to the casing. A cam follower is connected to and extends laterally from the second end of the insulating body member. The cam follower engages the cam surface in the first position and disengages the cam surface in the second position. The conductive member is mounted on the second end of the insulating body member and is positioned adjacent to the electrical contacts.

Abstract: A molded case circuit breaker having an operating mechanism including a collapsible toggle linkage, an operating handle and a movable frame. The collapsible toggle linkage includes a rectangular cross section knee pin non-rotatably held within an open rectangular slot in an upper link of the linkage. The operating handle pivots about a first pivot point when moving between ON, OFF and TRIPPED positions. The operating handle pivots about a second pivot point when moving to a RESET position thereby reducing the lateral force component of the operating springs of the operating mechanism for reliable return of the handle to the OFF position. Also, bifurcated movable contact fingers are provided for pivotal movement about a fixed pin to break contact welds and a trapezoidal cross section shaft interconnects the movable contact fingers.

Abstract: The contact bridge of a molded case circuit breaker is rotatably mounted in a bar by two springs arranged symmetrically from the rotation axis. Each spring is, on the one hand, anchored to the contact bridge, and, on the other hand, anchored to a rod housed in a notch of the bar. The same springs provide contact pressure and slowing-down of opening of the contact bridge at the end of repulsion travel by electrodynamic effect. The contact bridge bears on its edge cam surfaces which, at the end of opening travel, engage the anchoring rods to move them in the notches in the elongation direction of the tension springs. The energy of the contact bridge is thus taken up and stored in the springs causing slowing-down of the contact bridge. The profile of the cams can be chosen to enable reclosing of the contact bridge, this reclosing naturally being delayed by the slowing-down effect at the end of travel. The cam profile can also ensure latching of the contact bridge in the open position.

Abstract: The invention provides a clamping device which removably secures a body to a cable, the clamping device comprising a toothed, tapered cable gripping insert which fits into a stepped, tapered recess slot in the body. The cable gripping insert is retained in position by a T-shaped latching bar on the top of the insert which fits into transverse grooves in the body on either side of the recess slot. A clamped cable exits the recess slot at right angles to its entry, providing pivoting action. The cable attaching device is particularly suited for use with an attachment for use with a float switch assembly. Such an attachment may be used as a weighted pivot for a float switch or alternatively as an unweighted float for extending the range of an existing float switch assembly.

Abstract: A keyboard switch has a deformable membrane which, when deformed, enables electrical contact between a pair of contacts. A key stem is urged away from the deformable membrane by an elastic body. When the key stem is displaced sufficiently, the elastic body imparts a click feel. The key stem, when displaced a sufficient amount, deforms the deformable membrane to make the electrical contact.

Abstract: A single backpack is provided for allowing a simple conversion between an extended form for long duration hikes and a collapsed form for short technical climbs on ice and rock. The backpack comprises a frame that includes a pair of aluminum bars fastened to a frame surface of the pack. The main frame bars extend partially up the frame surface of the pack shell. The remaining distance from the top of the main frame bars and the top of the shell is spanned by extension bars which are held and fastened against the main frame bars. The main frame bars, with the addition of the extension bars, make the backpack a full sized large capacity hiking pack capable of bearing loads of 70 pounds or more. The backpack may be converted to a climbing pack by removing the extension bars from their fastened position and subsequently the shell collapses to the level of the lower main frame.
