A rotary knob for operating an electronically actuable deadbolt is described herein. According to some embodiments, the rotary knob includes a chassis, an outer wall rotatably coupled to the chassis about a central axis of the knob, a cantilevered beam attached to an inner surface of the outer wall and extending towards the central axis of the knob such that the beam is configured to rotate with the outer wall about the central axis, a circuit board coupled to the chassis, the circuit board including signal traces, and an electrical contact extending from the cantilevered beam in a direction toward the signal traces and electrically connectable with the signal traces. A controller of the rotary knob is configured to determine a position of the deadbolt based on at least the state of the electrical connection between the electrical contact and the signal traces.
