Abstract
The present invention is for an ambidextrous lockout switch system for use with a power tool. With the system of the present invention in place, a multi-step process must be carried out before the power tool can be activated. The system is adapted for the process to be carried out with either a left or a right hand. The present invention includes a handle body having a switch trigger or lever blockable by a barrier. The barrier is movable with either a left of a right lockout button, with the right lockout button being operably linked to the left lockout button. The system includes also a spring, which is mechanically coupled to the barrier. The spring effectively restores the barrier to a position in which the barrier blocks actuation of the switch trigger or lever.
