REK-43 RF4.500.478-09.02 low-current, electromagnetic, single-stable, non-polarized, sealed, subminiature relay, with two changeover contacts, is used to obtain an independent time delay. The time relay is used in circuits where it is necessary to automatically perform some action after a certain period of time. The relay mechanism is housed in a plastic housing, on the front of the relay, there is a setting sub-range switch and a time delay setting knob.
