ABSTRACT:
A switch device is mounted on the rear end of a conductive barrel body of a flashlight, and includes an actuating plunger movably disposed in a coupling member. An elastomeric cap member includes an annular insert portion interposed between a rear annular wall of the coupling member and the actuating plunger, and a cap portion. The cap portion has a depressible body and an annular connecting portion which extends forwardly in an axial direction and which is formed integrally with the insert portion to define an annular juncture therebetween. A block member extends radially and outwardly from the annular juncture to form a shoulder that faces rearwards, and has an outer peripheral surface distal to and radially spaced relative to the annular juncture. A socket portion extends forwardly from the depressible body so as to be plugged by a depressible plug end of the actuating plunger. A tubular retaining member includes an inner annular retaining portion that extends inwardly and radially from an inner surface thereof such that, once the retaining member is brought to engage the rear annular wall of the coupling member, liquid-tight abutments are established among the inner annular retaining portion and the annular connecting portion and the shoulder.
