The 'potential-free switching actuator with push-button function' receives and switches devices such as the bell. The special feature of this product is that when assigned in basic mode, only the 'push-button function' is used. The output is switched as long as the assigned button/sensor is pressed (function of a bell button). Even when resetting to the delivery state (reset) and reassigning a button/sensor in basic mode, only the push-button function is available. In comfort mode, all known and proven functions remain unchanged. The power is supplied via the mains. Voltages other than mains voltage can also be switched. The device is installed in the switch, junction, installation box or directly in the lamp cover.
