A wall-mounted dimmer may include an actuator assembly configured to translate a touch interaction with the dimmer into a desired dimming level. The actuator assembly may include a control interface having a resilient, deflectable membrane, a plurality of force-sensitive impedance members supported by the membrane, and an actuator configured to transfer a touch along the actuator to the membrane, causing the membrane to actuate one or more corresponding force-sensitive impedance members. The force-sensitive impedance members may be configured to make contact with corresponding ones of a plurality of open circuit pads supported by a printed circuit board. Each of the plurality of open circuit pads may correspond to a predetermined dimming level applied to a lighting load electrically connected to the dimmer. The control interface may be configured such that contact between the force-sensitive impedance members and corresponding ones of the open circuit pads is pressure sensitive.
