Abstract
Apparatus in a trigger grip switch assembly for sequential actuation of first and second electrical switch banks. First and second actuating elements each have a base portion, a switch-actuating arm extending from the base portion, and a resilient pressure-transferring arm extending from the base portion at an acute angle to the respective switch-actuating arm. The respective base portions are mounted for pivotal movement relative to the respective first and second switches and for presenting the switch-actuating elements in respective proximity to the first and second switches for actuation thereof upon base portion pivoting movement and for presenting the pressure-transferring arms in mutually overlapping relation with a distal end portion of a first pressure-transferring arm in contact with a medial portion of a second pressure-transferring arm. The pressure-transferring arms form between them an angle at least slightly greater than 30 degrees to provide an over-centered stable relationship. Pressure transferred by a trigger switch button to a distal end portion of the second pressure-transferring arm causes destabilizing sequential collapsing movement from the overcentered relationship for corresponding sequential actuation of the switches.
