Door communication switching actuator

Switching on a light in the staircase and opening the garage door using the Gira home station.

The switching actuator is used to carry out switching functions on the Gira home station or via an unassigned call button, for example switching on/off a staircase light or opening the garage door.

Together with a commercially available doorbell transformer, the switching actuator can also be used to control additional door openers, for example, for a driveway gate, or the door of a side entrance.
