A rotary actuator assembly includes a rotary actuator having a rotary body on a capacitively-sensing detection surface of the touch panel. A sensor ring coupled to the rotary body includes on a first ring surface includes alternately arranged contact surfaces and insulating surfaces and on a second ring surface includes a circumferential metal surface that is electrically connected to the contact surfaces. A sliding contact includes a contact pad and a contact spring connected together. The contact pad forms an electrical contact point fixed at a position of the detection surface. The contact spring contacts the contact surfaces and the insulating surfaces in alternation as the sensor ring rotates with rotation of the rotary body whereby a variable electrical signal is generated at the contact point. The electrical signal is detectable by the touch panel and the touch panel includes a mutual capacitance touch sensor assembly.
