<p>A lamp replacement tool (10) provides for poisitively captivating lamps for ease of removing or inserting lamps (12) from or into the type of a lamp housing (14) that forms part of a flush mounted push button switch used in aircraft cockpit control panels. The tool includes upper (34,35) and lower blades (32) extending from a handle member (26) in spaced apart parallel relationship. The lower blade (32) is formed with a forked end portion (40) having a U-shape (41) for engaging with a flange (22) formed on a base portion (16) of the lamp and for embracing the base portion. The upper blade (34,35) is formed with either a V-shaped portion (44) or an aperture (43) for engaging with a base contact (24) protruding from one end of the lamp. The upper blade (34,35) terminates in an angled lead-in (47,48). The lead in provides a smooth surface for sliding over the base contact as the upper blade flexes over the base contact when the tool is pushed into engagement with the lamp. The lamp is locked or captivated between the upper and lower blades of the tool when the U-shaped end of the lower blade embraces the base portion and engages with the flange and the interior surfaces of the V-shape or aperture portion of the upper blade engage the periphery of the base contact.</p> |
