ABSTRACT:
A hand held spotlight includes a sealed beam enclosure together with one or more detachable handles. The detachable handles each include a latching mechanism capable of translating a magnet between a first position and a second position. A magnetically-actuated switch within the enclosure is used to turn off and on the light circuit. The handle is detachably mounted on the enclosure in a particular position so that the magnetically-actuated switch within the enclosure may be opened and closed by the magnet in the handle. In the preferred embodiments, a single enclosure may be utilized with either a pistol-style grip or a lantern-style grip. The ability to form the beam enclosure without penetrations is particularly useful in providing watertight and explosion-proof spotlights.
