Load commutation device for e.g. home automation field, has retarding unit that retards and damps movement of movable contact unit of relay, where retarding unit is of mechanical spring type and is connected to movable contact unit

摘要

The device has a relay (2) with a fixed contact unit (3), a movable contact unit (3`) and a relay coil (4). An electronic device (7) controls a control interface (6) and two input connections of a power circuit. A retarding unit (8) retards and damps the movement of the movable contact unit (3`). The unit (8) is of mechanical spring type and is connected to the contact unit (3`).
