Turning on the radio switch (have a Home Easy HE878 paired)) was not working anyway sometimes, sometimes. Off did not work. Open housing and the switch briefly bridged with a screwdriver, then worked from also turning off and on. Given the choice to replace the defective mini switch from solder and a new one or to throw the switch to the ton, I have opted for the latter. Have now resorted to HomeMatic product, is more expensive but works fine.
