A switch assembly for an electrosurgical instrument includes a switch housing, a switch, a first biasing member, and an additional biasing member. The switch is disposed within the switch housing and movably disposed between an activated position to initiate delivery of electrosurgical energy and a deactivated position to terminate delivery of electrosurgical energy. The first biasing member is selectively positionable adjacent the switch and in communication therewith. The first biasing member includes a first thickness that provides a first resistance to resist movement of the switch between the activated and the deactivated positions when positioned in the switch housing. The additional biasing member is selectively interchangeable with the first biasing member. The additional biasing member includes a different thickness that provides a different resistance to resist movement of the switch between the activated and the deactivated positions when positioned in the switch housing.
