Claim 11:
12. A rotary slide assembly (1) with a rotary slide device (2) comprising a housing (3), a rotary slide chamber (4) and a rotary slide rotor (5), wherein slides (7) are arranged radially movably in slide receiving areas (6) in the rotary slide rotor (5), wherein one or more of the slides (7) themselves or one or more of the slide receiving areas (6) in their interaction with the slide or slides (7) are used to generate a requestable electric or electronic signal for detecting a wear state of the slide or slides (7), wherein detection of the wear state is performed when the rotary slide assembly (1) is at a standstill and/or during operation of the rotary slide assembly (1), further comprising a sensor (S) which consists of a voltage source (17) and a conductor (18) which connects the voltage source (17) in the sense of a short circuit, wherein the electrical conductor acts in a switch-like manner upon reaching a wear limit, and the switching state is detected via corresponding evaluation electronics, wherein, further, the conductor is arranged in the slide (7) and is ultimately exposed with increasing wear of the slide (7), wherein at a certain wear state of the slide (7), the conductor (18) establishes an electrically conductive connection with the voltage source (17), wherein ends of a voltage or switching circuit, which are bridged in the closed position by the electrically conductive conductor in a switch-like manner, are exposed in the chamber wall along which the slides slip.
