Abstract: An improved light adapted to be connected to a wheel of, e.g., a bicycle. In preferred form, the light is fixed to the wheel in a manner that orients the light's battery on an axis positioned substantially radially of the wheel, and that orients the light's battery radially inward of the light's bulb relative to the wheel's axis. A switch spring is provided in the light's housing that normally biases the battery out of electrical contact with the bulb when the wheel is not rotating, i.e., when the bicycle is not in use, but which permits the battery to be biased into electrical contact with the bulb in response to centrifugal force when the wheel is rotating, i.e., when the bicycle is in use. Thus, the light turns off automatically when the bicycle is not being ridden, and turns on automatically in response to centrifugal force when the bicycle is being ridden, when the light is mounted on a bicycle's wheel.

Abstract: In a pocket torch the bulb itself is used as the switch. It tilts between two positions of stable equilibrium, while being confined resiliently between the casing and the battery.

Abstract: A diver's flashlight having a unitary case with a closed transparent end for light transmission, the other end being sealed by a threaded plug which also serves as a switch.

Abstract: A flashlight assembly including a cylindrical housing defining a battery compartment and a separated lamp compartment with a circuit controlling switch located entirely on the outside of the cylindrical enclosure, the lamp compartment lying in a separate part of the cylindrical enclosure which is threadedly connected to the main portion of the enclosure, there being an electrical connector between the switch unit and the lamp and socket unit which extends from the switch on the outside of the enclosure to the interior of the lamp compartment and remains entirely outside the battery compartment.

Abstract: A flashlight is disclosed that is comprised of a disposable battery section and a reusable head section detachably connected to one another. The battery section comprises one or more batteries enclosed in a low-cost tube of cardboard or the like, the batteries being disposed in end-to-end relation. The tube is formed with an aperture exposing the metal casing of the lowermost battery, and a strip of aluminum foil, coated with a stratum of pressure sensitive adhesive, is applied along the length of the tube and over the aperture. The head is detachably connected onto the upper end of the tube and is of a conductive metal to complete a circuit with the aluminum strip. The flashlight is turned on by pressing the aluminum strip over the aperture to close contact with the battery.

Abstract: The switch includes a slide, mounted for movement along the housing between first, second and third positions, and carrying a depressable pushbutton. A flexible contact is movable by the pushbutton to a position wherein it is operatively connected to a fixed contact to complete the electrical circuit. The pushbutton and the flexible contact each have corresponding camming and non-camming surfaces thereon which respectively interact to move the flexible contact towards the fixed contact. The corresponding camming surfaces interact only as the slide is moved from the second to the third position. The corresponding non-camming surfaces interact only when aligned and the pushbutton is depressed. Since none of the surfaces operatively interact as the slide is moved from the first toward the second position, wearing of the interacting surfaces is substantially reduced.

Abstract: A slide switch designed to be attached to the barrel of the flashlight by a pair of screws which serve the further function of interconnecting the switch to the electrical circuit of the flashlight. The switch body is of insulating material. It includes a pair of side ears protecting the switch operator and a pair of screw holes through the body. Two leaf springs constituting the contact elements include reentrant tabs extending through the screw openings of the body whereby the reentrant tabs engage both the shank and the underside of the head of the mounting screws.
