Abstract: An operator control apparatus, in particular a remote control apparatus is provided, comprising a splashproof housing and at least one operator control device which comprises an input assembly having a pushbutton head manually displaceable along a longitudinal axis, a rotary member rotatable about an axis of rotation and a coupling mechanism via which a linear movement of the pushbutton head is translatable into a rotary movement of the rotary member, wherein a signal transmitter is held to the rotary member in a rotationally fixed manner, which signal transmitter interacts with a sensor element arranged in the housing. In order to improve the operator control apparatus in such a manner that the input assembly may be mounted with ease and, if required, replaced with ease, the input assembly is insertable in a mounting direction into an exterior recess of the housing and is removable from the recess when required.

Abstract: An input assembly for inputting a control command for an operator control apparatus is provided, comprising a pushbutton head manually displaceable along a longitudinal axis and a movable signal transmitter which is coupled to the pushbutton head via a coupling mechanism. The input assembly comprises at least one latch element having a latch head which has associated therewith at least one latch depression which the latch head enters when the pushbutton head has reached a predetermined stroke position. The at least one latch element has associated therewith a travel groove oriented parallel to the longitudinal axis, which travel groove the latch head of the latch element enters permanently. The at least one latch depression associated with the latch element is arranged in the travel groove. An operator control apparatus having such an input assembly is also provided.
