Abstract
A proximity switch is described, specifically a capacitive proximity switch, with two signal transmitters (1, 2) and with one signal receiver (3), a first signal output (4, 5) of each of the two signal transmitters (1, 2) being connected to one another and to a first signal input (6) of the signal receiver (3), and a second signal output (7, 8) of each of the two signal transmitters (1, 2) being connected via a respective signal transmission path (9, 10) to a second signal input (11) of the signal receiver (3), and at least one of the two signal transmission paths (9, 10) can be influenceable by an actuating object.
