Abstract
A portable light includes a light, a battery, and a switch having an "on" position and an "off" position. The switch in the "off" position prevents the light from being illuminated and the switch in the "on" position directly connects the light to the battery to cause the light to be illuminated. The switch includes a first interdigitating member. A bracket for mounting the portable light includes a second interdigitating member in interconnecting relationship with the first interdigitating member on the switch. The interconnecting relationship between the interdigitating member moves the switch to the "on" position when the light is removed from the bracket.
