Abstract
The invention relates to a rotary/push-button controller having a controller ring (18) which can be rotated about a rotation axis (7) and is arranged such that it can rotate on a holding cylinder (6) which is arranged coaxially within the control ring (18). In this case, the holding cylinder (6) is provided at its end with an input and/or display field (14), and the control ring (18) and the holding cylinder (6) can be moved axially with respect to the rotation axis (7) against a spring force from a neutral position to a switch position which operates a switching element. The input and/or display field (14) is mounted so that it can rotate about the rotation axis (7). A rotary transmitter ring is arranged coaxially on the control ring (18) and is arranged coaxially alongside a rotary transmitter (17) which is firmly connected to the holding cylinder (6) with the relative rotation position of the rotary transmitter ring with the respect to the rotary transmitter (17) being recordable.
