A switch assembly for engaging a switch of an electronic device includes a rotatable knob having an axis of rotation, a pin mechanism engaged with the rotatable knob, and a slider body. The pin mechanism includes a pin, the pin being offset from the axis of rotation of the rotatable knob. The slider body is shaped to include a slot in which the pin of the pin mechanism is positioned and a switch recess shaped to receive and selectively contact the switch of the electronic device. Rotation of the rotatable knob in a first direction causes the slider body toward contact with a first portion of the switch to urge the switch into a first position, and rotation of the rotatable knob in a second direction causes the slider body toward contact with a second portion of the switch to urge the switch into a second position.
