A surgical instrument including a handle assembly and an end effector, including a first jaw pivotably coupled to a second jaw, is disclosed. The handle assembly may comprise a jaw position sensor comprising a switch, a closure trigger, and a clamp spring actuatable by the closure trigger. The closure trigger may be configured to: rotate between a first position and a second position, wherein the first position corresponds to the first and second jaws in an open position and the second position corresponds to the first and second jaws in a closed position, and activate the switch of the jaw position sensor at a predetermined rotated position. The clamp spring may be configured to: cause the first and second jaws to transition between the open position and the closed position, and apply a force to the first and second jaws.
