Abstract

174,480. Oldham, O., (trading as Oldham & Son), Oldham, G., and Oldham, J. Nov. 12, 1920. Switches without quick action for use with miners' safety and other electric hand lamps and torches comprise a screw operating - member m mounted in a boss o of the casing and carrying an insulated disc contact r for bridging engagement with two or more spring-pressed plunger contacts i mounted in an insulating - housing f secured to the block a and connected to the terminals of the circuits by means of plates c engaged by the inner ends of the plunger springs j. The plunger contacts may be fitted upon the case of the accumulator.
