Abstract: A multi-facetted translucent ball surrounds a lamp which is suspended from an earring clip by a flexible tubular metal shaft which has a wire running there through. The earring clip is U-shaped and has a pair of opposed legs which are spread resiliently apart when the clip is engaged on ear with the lobe between the legs. One leg carries, connected to the wire, a cup for holding a wafer battery. A U-shaped support secured to the clip carries a contact opposite the cup in a position so that the cup is urged toward the contact for engaging opposite terminals of the battery upon spreading of the clip.

Abstract: A switch device for use in a wristwatch. The device comprises a switch housing and a cavity defined within the switch housing. The cavity has a side wall with at least a portion thereof being arcuately extending, a top wall and a bottom wall. A spherical displaceable element, of magnetically attractable material, is located for movement within the cavity. The side wall, top wall and bottom wall are spaced apart a distance sufficient to permit free displacement of the displaceable element therebetween. At least one magnetic element is associated with the cavity and located in a portion of the side wall whereby to retain the spherical displacement element thereto by magnetic attraction when the spherical element is displaced thereagainst in the cavity. The spherical element, when retained by the magnetic element, is dislodged therefrom by an external force created by a predetermined movement of a wearer's arm to release the spherical element in the cavity by gravity.

Abstract: Disclosed is a solid state watch having an electro optical display which is selectively actuated by a gravity switch contained in the watch casing and positioned such that upon a displacement from a horizontal of the watch the display is actuated. A preferred embodiment utilizes a triangular-shaped cavity having a ball-shaped conductor movably contained therein for engaging a pair of electrical contacts within the cavity for coupling power to the display. Furthermore, the displacement of the watch from horizontal must also be within a selected orientation range.

Abstract: A multiple pole bushbutton rotary switch has axial as well as rotary travel. A first dimple in the back of the rotor of a stem and rotor assembly is rotatable over a desired number of position indicating detents for selective positioning of the rotor. The stem is then pushable on its axis to make a second dimple located on the opposite surface of the rotor travel into a second detent on a substrate and make electrical contact between the rotor and contact within the second detent which is preferably coupled to circuit conductors on the substrate. An embodiment of the pushbutton rotary switch is particularly useful for controlling a plurality of different time-date setting functions of electronic watches with a single switch mechanism.

Abstract: The subject safety switch insures that the chuck key has been removed from the chuck prior to operation of the drill press. A slide "on-off" switch is engaged by a guard that prevents the sliding movement necessary to turn the switch on. The guard of the safety switch is not part of the electrical circuit, but rather is a mechanical addition which prevents operation of the electrical circuit. The socket is formed in the housing adjacent the guard. The chuck key is inserted into the socket to engage the guard and remove it from the path of travel of the switch to permit the switch to be shifted between the on and off position. The socket is keyhole shaped, whereby insertion of the chuck key therein will force the chuck to seat within the lower narrower aperture thereof.

Abstract: A diaphragm type pushbutton actuator switch with self-contained contacts includes a pop-in head. The main switch body is mountable in a substrate or housing with an opening provided for the head. The head is then press-fittable into the main switch body for retention therein. With the head retained in the main switch body, it is movable therein to make or break electrical contact upon actuation.

Abstract: Terminals within a digital wristwatch which normally require closure by pressing a button on the side of the watch in order to render visible the display are arranged to be automatically closed by a magnetic inertial device within the watch casing. The magnetic inertial device includes a guide tube and a conducting ball held at one end of the tube by a permanent magnet. The terminals to be closed and thus render visible the display on the watch are positioned in the other end of the guide tube so that by flicking the wrist, the ball is shaken loose from the magnet and will make momentary contact with the terminals, thereby rendering the display visible. A reading can thus be taken without requiring use of the other hand to operate the normal manual press-button switch on the side of the watch.

Abstract: A swimming pool touch pad seats on a swimming pool wall and is adapted to close an external electric circuit when contacted by a swimmer. The pad includes a nonconductive baseplate adapted to be mounted on a swimming pool wall. A normally nonconductive generally planar pressure sensitive elastomeric pad is seated on the baseplate and is adapted to become selectively conductive through the pad from the front to the rear surface upon application of pressure by a swimmer. When conductive it will provide an electrical current path in the area of pressure application. Electrodes secured to the front and rear surfaces of the elastomeric pad and insulated conductors connected between the electrodes and the external circuit complete the electrical path from the elastomeric pad to the external circuit. A nonconductive waterproof flexible cover member is secured to the baseplate and covers the elastomeric pad with the insulated conductors passing through the cover member.

Abstract: A mouth held switch assembly which is adapted to be connected to an electrically actuated surgical implement. The switch assembly is designed to be operated only by a clamping movement of the front incisors of the user. The switch assembly includes an elongated, thin walled, L-shaped, tubular housing, one end of which fits into the mouth of the user. A pair of electrical contacts formed on spaced blades are sealed in the leg of the housing which is insertable in the user's mouth. The contacts are connected to electrical leads extending out of one end of the housing. A portion of the housing is weakened adjacent the contacts with the weakened portion being protected by guards which permit only the incisor teeth of the user to contact the weakened portion of the housing, when the housing is inserted in the user's mouth. When the user bits down on the weakened portion of housing, the contacts are closed, thereby actuating the surgical implement.
