The RTS05 call button is a capacitive proximity switch (sensor wall switch) for wall mounting inside dry buildings.

A wireless signal is transmitted through proximity or by briefly touching the sensor surface. It can be used in combination with the RCP25 pager or the RCP24 radio bell, as a convenient way of calling people.

There is also an option to link it to nursing care systems, e.g. as a call button for nurse call sets.
