ABSTRACT:
In a door jamb switch of the type having a first member adapted to be fixedly secured onto a door jamb of a motor vehicle, a switch element having a first actuated condition and a second actuated condition and a plunger mounted for reciprocation in the fixed first member along an axis between a first, door opened, position with the switch element in its first actuated condition and a second, door closed, position with the switch element in the second actuated condition there is provided an improvement. The plunger carries a generally cylindrical water deflector sleeve concentric with the movable axis of the plunger and telescoped around the plunger mounting sleeve. This deflector sleeve is secured onto the plunger at its outer end and is free standing at its inner end so that the sleeve reciprocates over the open end of the mounting sleeve with movement of the plunger to prevent the flow of water into the open end of the mounting sleeve.
