ABSTRACT:
A potentiometer is disclosed that provides a user with tactile feel while making adjustments. The potentiometer includes a housing having a central bore with a rotor extending therein. A knob having a protrusion is operably connected to the rotor along with a wiper. A detent member having a lobe attachment segment and a fixed segment is operably connected to the housing. The lobe is deflected by the knob protrusion while the ring is compressed by forcing the lobe attachment segment towards said fixed segment. Furthermore, attached to the housing is a base plate carrying a resistive strip engaged by the wiper.
