Abstract
A switch mechanism with a safety member for operating a tool or a weapon which reduces the probability of inadvertent operation. The switch mechanism comprises a trigger and a safety member disposed adjacent to the trigger for preventing the trigger from contacting an actuation switch. The safety member is shaped such that when it is positioned in a first position, it prevents the trigger from contacting the switch. In addition, the safety member is shaped such that when the safety member is positioned in a second position, it allows the trigger to contact the actuation switch.
