Relay switch insert with floating contact, 1-channel


The relay switch insert with floating contact, 1-channel switches electric circuits separated from voltage for lighting and motors. Using a JUNG HOME room thermostat display or a KNX RF push-button, you can, for example, control underfloor heating systems and electrothermal valve drives. The switch insert can be installed in a commercially available wall box (e.g. Kaiser 1055-02) according to DIN 49073.
