摘要:
A push handle switch lampholder pushes a lower conductive plate to move like a see-saw by pushing a push handle to move back and forth and determines whether or not to pass a current to an upper conductive plate, so as to control the ON or Off of a light emitting element. In addition, a set of hooks is provided for connecting a power cable for an electric connection without the need of tying an UL knot to expedite the wire connection conveniently and securely. The invention can reduce the number of components and the volume while achieving the effects of lowering the manufacturing, storage and transportation costs, and improving the overall service life of the lampholder.
摘要:
A lighting device including a test device for testing the proper operation of a primary and a secondary power supply alternatively providing electrical power to the light. The test device is attached to a bracket using a single fastener such as a nut and the bracket is attached to a receptacle for the light using a different single fastener, such as a pop-rivet or screw.

A light socket having a standard contact and switch arrangement for standard operation with three-way incandescent light bulbs. In addition to the standard main switch, the socket also includes a secondary mode switch operatively connected to the appropriate terminals such that placing the mode switch in a first position will provide proper operational sequence with a three-way light bulb, while placing the mode switch in a second position will provide the proper operational sequence for a one-way light bulb. This mode switch may also be provided in an adapter which is formed to be received within the receptacle of a standard three-way light socket, and which also includes a standard receptacle for the receipt of the light bulb.

An incandescent lamp socket comprises a housing for receiving the base portion of an incandescent lamp and switch means for selectively connecting the lamp's contacts to a source of electrical energy. Such switch means comprises a rotatably mounted cylindrical sleeve which surrounds the socket housing, and means responsive to rotational movement of the sleeve relative to the housing for selectively connecting the lamp contacts to the energy source. Preferably, such connecting means comprises a planetary ring gear disposed along the interior wall of the sleeve, a cooperating pinion gear mounted for rotational movement on the socket housing, cam means rigidly coupled to the pinion gear and rotatable therewith, and electrically energized cam follower means, movable in response to the cam means to selectively energize certain socket electrodes which are connected to the contacts of a lamp supported by the socket housing. According to another embodiment, the pinion gear is used to control the output of a conventional potentiometer which, in turn, controls lamp power.

A squeezably actuated electric switch is disclosed comprising a standard push on - push off electric switch mounted in a housing; and a flexible, hollow squeezable switch member filled with a liquid attached to the housing. The squeezable switch member has an expandable surface portion in contact with the push on - push off switch actuator end face. The expandable surface portion bulges upon squeezing the body of the switch in any position forcing the switch actuator inward to throw the push switch. The housing may comprise among other things an incandescent lamp socket.
