ABSTRACT:
A rotary potentiometer device (1) has a rotary potentiometer (4) disposed within a housing (2) and a handle (7) above the housing (2) for rotating a resistive disk (6) of the rotary potentiometer (4). A latching device latches the handle (7) with the upper side of the housing (2) in predetermined rotation positions. At least one spring-loaded latching nose (16) protrudes above the upper side of the housing (2) and cooperates with latching troughs (18) in the lower side of the handle (7). No additional individual components are necessary for making the latching device. The spring-loaded configuration urges the latching nose towards a latched position defined by the latching troughs when it is deflected out of its latched position.
