SAFETY SWITCH FOR LAMP INCLUDING A LIGHTSOURCE CAPSULE

摘要

A safety switch for a lamp having an outer envelope with a light source capsule mounted therein. The lamp has a base for connection to an electrical circuit via a mating socket and has in-leads appropriately connected to the base and to the light source capsule whereby electrical power can be supplied to the light source. A fuse is operatively mounted to one of the in-leads in the base. The safety switch is mounted in the outer envelope and tensioned thereagainst whereby breakage of the outer envelope causes the safety switch to release and electrically contact the in-leads causing a short circuit and opening the fuse, thereby removing power from the capsule.
