The switche are of four-poles type, with two closing contacts.
The switches are appropriate for safe ON/OFF switching of various machine tools or electric devices, as they ensure automatic protection against unwanted start, when power supply returns after a network failure. The power failure relay is factory built-in, without own output contacts, the operating voltage is ensured by the load-side contacts of the switch. In case of power failure, the relay disconnects the controlled device from the power supply line. Re-start is only possible with repeated operation of the green pushbutton, by the user.
Attention! A device must be connected according to the diagram on the side of the housing:

The version is equipped with a special cover, functioning like an emergency button. Upon being actuated, it produces a locked stop.
The device can only be re-started after repair of the fault, by lifting the cover and thus resetting the error condition.
