ABSTRACT:
A miniature flashlight with solderless connections for electrical circuitry capable of illuminating a lamp by the squeezing of a flexible case holding said circuitry. The circuitry includes a spring switch arm capable of being depressed by squeezing said flexible case to achieve electrical communication between two batteries and complete the battery circuit in order to illuminate the lamp. The spring switch arm having a portion thereof in continuous contact with a positive terminal of one battery and having a portion being centrally hinged so that upon squeezing said flexible case the spring switch arm is limited in its bending to a portion between said hinge portion and a free end thereof to prevent inadvertent lighting of the lamp. The spring switch arm will slightly move against the positive terminal when pivoted whereby to self-clean the terminal during use. The batteries, lamp and spring switch arm are held by an insulative cartridge that holds the batteries in side-by-side relationship. The cartridge has flexible end walls which resiliently retain the batteries and clamp the lamp lead wires and spring switch arm by means of a longitudinal compressive force enabling the electrical connections to be solderless.
