Abstract
A control element includes a switching element, an operating element for operating the switching element, a printed circuit board, and an electrically conductive sensor element of a capacitive proximity sensor integrated in the operating element. The electrically conductive sensor element is designed to be electrically conductively connected to the printed circuit board.
Claims13
A control element comprising:
- a printed circuit board;
- an operating element for operating the control element;
- and
- an electrically conductive sensor element of a capacitive proximity sensor integrated in the operating element and fixedly connected along a vertically arranged side wall of the operating element, electrically and contactingly connected to the printed circuit board;
- wherein the control element is a pushbutton switch, and the operating element is linearly movably mounted relative to the printed circuit board.
