The Homematic wireless switch actuator enables switching of
battery-powered devices. The actuator controls a connected load in
accordance with the wireless commands it receives. The device can
be controlled by buttons, remote operations or from a software inter-
face. In addition, it is possible to control actuators with sensors that
are taught in. The sensors send (like a button) a command when an
event occurs. More information is provided in the instructions for the
respective sensor.
The actuator, which runs on a DC voltage of between 5 and 15 V,
can handle a switching current of up to 3 A (at max. 20 V) via an
open-drain output. It is capable of controlling loads and relays (or
similar) as well as switching inputs (L active).
