Abstract
A circuit for detecting a state of at least one electrical actuating element is described. The circuit has a signal input for receiving an input signal representing the state of the actuating element, a signal output for emitting an output signal representing the state of the actuating element, a control output for emitting an activation signal for an evaluation unit, to change over the evaluation unit from an inactive operating state to an active operating state, and a control unit. The control unit is connected to the signal input on the input side and to the control output on the output side and serves for generating the activation signal in a manner dependent on the input signal. The input signal at the signal input is an analog signal, the control unit generating the activation signal for the evaluation unit if the input signal lies within a predetermined range.
