Abstract

The invention relates to a rotating actuator/pressure actuator (13) comprising a ring-shaped rotary transducer (5) consisting of an inner ring and a rotary ring with a handle (1) and which can rotate around the inner ring about an axis (z) and which is displaceably arranged in a linear manner along the axis (Z) in relation to a housing (11), in addition to an inner part (touchpad 2) which is arranged in an inner area (12) of the ring-shaped rotary transducer (5) and which is displaceable in a linear manner along the axis (z) together with the ring-shaped rotary transducer (5) in relation to the housing (11). Linear displacement of the handle (1) and/or inner part (touchpad 2) triggers a push-button function. According to the invention, the rotary transducer (5) and inner part (touchpad 2) are arranged in a pan-shaped guide element (7) which is arranged in a linear displaceable manner along the axis (z) in the housing; the inner ring of the rotary transducer (5) is rotationally fixed in the guide element (7); the rotary transducer (5) and the inner par (touchpad 2) are connected to the guide element (7) in such a way that they are not displaceable along the axis (z) and the guide el…
