ABSTRACT:
A high cycle life switch assembly having a seal positioned between a trigger and a non-tactile switch with a snap dome positioned exterior of the seal and engaged by the trigger to give a high tactile feedback. The snap dome is mounted on the trigger and an actuator rod extends between the snap dome and the switch, through the seal, to apply an actuation force to the switch when the trigger is moved toward an actuating position. The actuator rod extends through an aperture in the seal and is slidably and sealably disposed therein to apply no force on the seal as the actuator rod is moved to actuate the switch located behind the seal.
