A sensor comprising:
- a base, the base comprising:
- a bearing;
- and
- a sensor arranged in the base;
- and
- a lever rotationally deflectably mounted in the bearing, the lever comprising:
- a shaft mounted in the bearing and connected to the base;
- and
- an encoder,
- wherein the sensor is configured to detect the encoder,
- wherein the lever is plastic molded as a single piece, and
- wherein the base and the bearing are plastic molded as a single piece together
- wherein the bearing comprises multiple detent hooks and/or detent projections arranged in encircling fashion on an inner shell of the bearing and formed as a single piece with the bearing,
- wherein the multiple detent hooks and/or detent projections are configured to directly or indirectly hold the shaft
- wherein the multiple detent hooks and/or detent projections comprise two mutually spaced-apart rows of detent hooks and/or detent projections arranged in encircling fashion on the inner shell of the bearing formed integrally with the bearing, and
- wherein the two mutually spaced-apart rows are configured to be substantially parallel to one another.
