Abstract
Abstract A reusable light comprising a housing configured to operatively retain a voltage source therein having an extended bulb assembly mounted on one end thereof and a switch pivotally mounted on the opposite end thereof, the extended bulb assembly comprises an elongated hollow sleeve having a mounting member attached on one end thereof to attach the extended bulb assembly to the housing and a bulb housing having a light source disposed therein attached to the opposite end thereof, a first conductor including a first and second conductor element extending substantially the length of the flexible light coupled to the light source, a second conductor disposed within the hollow sleeve being coupled to another portion of the light source and a removable cap to selectively house the extended bulb assembly, the switch movable to operatively engage the first conductor means to selectively close the circuit and activate the light source.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
263 words
A switch for use with a hand held battery powered device such as a light wherein the hand held device comprises an outer housing configured to retain a battery voltage source therein and having a light mounted on one end thereof and said switch pivotally mounted on the opposite end thereof and a conductor element extending substantially the length of the outer housing electrically connected to the light; said switch comprising a body including an arcuate cam member having a compound radius formed thereon forming a first and second conductive cam surface, said first conductive cam surface comprising a first substantially flat contact disposed to selectively engage said conductor element and said second conductive cam surface being substantially arcuate to engage the battery voltage source, said arcuate cam member being movable between a first and second position such that said first conductive cam surface is isolated from said conductor element when said switch is in said first position to deactivate the light and said first conductive cam surface engages said conductor element when in said second position to couple said conductor element to the battery voltage source to actuate the light, said second conductive cam surface engaging the battery voltage source off center relative to the longitudinal axis thereof opposite said conductor element when said switch is in said first position to lock said switch in said first position and engaging the battery voltage source off center relative to the longitudinal axis thereof adjacent said conductor element when said switch is in said second position to lock said switch in said second position.
