Estimating the term…
A battery-powered lamp, such as a traffic hazard warning lamp has: A. a casing formed with ledges for location thereon of the bottom edges of the batteries to retain the batteries in the casing, a fixing bolt, extending through the casing, serving to prevent disengagement of the batteries from the ledges; B. said casing having apertures in two opposite sidewalls, each said apertures accommodating a respective lens which is a tight friction fit therein and may have ratchet-like teeth engaging with the material of the casing to retain the lens in position; and C. a switch in the form of a terminal strip engaged by terminals of the batteries, said strip being longitudinally slidable and having a bridging portion which is in or out of register with a stationary contact according to the position of the strip.
An electric lamp having a switch assembly comprising a support carrying a conducting protuberance, and a slidable conductive strip member mounted for longitudinal sliding movement relative to said support and having a bridge portion disposed to register with and form a bridge over said protuberance to provide an "off" condition of the switch, in which there is no contact between the slidable strip member and the protuberance, longitudinal movement of the slidable strip member serving to bring said slidable strip member, adjacent to the bridge portion thereof, into contact with the protuberance to provide an "on" condition of the switch.
