ABSTRACT:
A tritium switch that can be easily fitted to standard laser sight that can be easily adapted to fit standard semi-automatic handguns or to standard military rifles such as an M-16. The switch is also useful as a safety interlock switch on machinery requiring electrical power. With a firearm, the switch allows the user to engage and disengage the laser sight without the necessity of reaching a special button or part of the weapon. The switch can be fitted to a standard trigger of the weapon so that the switch can be thrown as the user readies the weapon for firing. The switch is fabricated from using commercially available parts. The emitter portion of the switch, that is, the tritium vile requires no power and the detector portion, a low power consuming photoelectric cell, can be powered by commercially available batteries, providing a long service life before needing to be changed.
