The invention relates to a pocket lamp having an electric battery, a light bulb, a housing one of whose walls is made of a plastic material and supports the light bulb and forms a reflector and conductors forming with the light bulb and the battery an electric circuit closed by a switch. The switch has a knob sliding along the wall of the housing and which can be placed in two stable positions which are determined by a resilient appendage belonging to the aforementioned wall and co-operating with a protuberance formed in the knob. Application to pocket torches having a flat electric battery.

DETAILED DESCRIPTION What is claimed is: 1.
An electric pocket lamp including an elongated molded plastic battery housing having a surrounding wall at one end thereof and an integrally molded concave plastic reflector supported by the wall and closing said one end of the housing, a light bulb centrally mounted in the reflector and having two terminals, an electric battery means positioned in the housing, the battery means having a resilient blade permanently attached to each of positive and negative poles thereof, the blades extending from the battery at the one end of the housing such that one resilient blade is biased into direct contact with one terminal of the light bulb, the wall of said housing having an elongated slot adjacent said one end, and a molded plastic slider means having a thumb-actuated knob in sliding contact with the exterior surface of said wall and a portion extending through said slot to the interior of the housing, the slider means being reciprocally movable in said slot and said interior portion of the slider means being operatively engageable with the other resilient blade for selectively opening and closing an electrical circuit between the other blade and the other terminal of the light bulb in response to reciprocal movement of the slider means in the slot, wherein the improvement comprises: a resilient plastic appendage molded integrally with the housing and extending from the interior surface thereof in the vicinity of the slot in said wall and cooperating with the slider means to determine two positive detent positions for the slider means corresponding to the opening and closing of said electrical circuit.
2.
An electric pocket lamp according to claim 1 comprising said light bulb being mounted directly in the molded plastic reflector without any other metal part, and wherein said electric circuit is closed by said other resilient blade making direct contact with the other terminal of the light bulb.
3.
An electric pocket lamp according to claim 1 wherein the one terminal of the light bulb comprises a threaded metal shell and the other terminal comprises a central base terminal separated from the shell by insulating material, the one resilient blade being biased into direct contact with the shell, and the other resilient blade being biased into direct contact with the central base terminal when the slider means is in said second position
