Abstract
A switch assembly includes a switch housing, a first switch subassembly, and a second switch subassembly. The first switch subassembly includes a shaft and a toggle button. The shaft is disposed within the switch housing and has a proximal end portion and a distal end portion. The shaft is pivotable relative to the switch housing about at least one pivot axis to actuate at least one function of a surgical instrument. The proximal end portion of the shaft includes a magnet. The toggle button is non-rotatably connected to the distal end portion of the shaft. The second switch subassembly includes a safety bar and a post. The safety bar is axially movable within the switch housing. The post extends through the safety bar such that movement of the safety bar along a longitudinal axis thereof moves the post between a firing position and a non-firing position.
