ABSTRACT:
A tool for use in removing and replacing a bulb of a push-button type actuatable switch comprises a tool body having a first end defining a bulb-accepting opening. A plurality of tines surround at least a portion of the opening. When the tines are in a first position, the opening is sufficiently large to accept a bulb. When pressed inwardly, the tines reduce the size of the opening and engage a bulb located therein. Movement of a sleeve over the outside of the body presses the tines inwardly. In one embodiment, a flexible sleeve is located in the opening for gripping and protecting a bulb. A stop extends into the insert, limiting the extent to which a bulb may be pressed into the tool. An opposing end of the tool may include a prong or blade for engaging and removing a lens cover over a bulb.
