Eltako wireless switch, 80x80mm exterior, frame inner dimensions 55x55mm, 15mm high. Generates energy for radio telegrams even when pressed, thus no connection cable and no standby loss. With single and double rocker. Smart Home sensor. Included in the delivery are the frame R, a single rocker W55, a double rocker DW55 (all in the same color), a mounting frame BRF, the mounting plate HP, the radio module, and an adhesive film. A wireless switch with a single rocker can send two evaluable signals, while a switch with a double rocker can send four. The mounting plate can be screwed onto a flat surface or adhered to the wall, glass, or furniture using the included adhesive film. Above a 55mm switch box, the existing sleeves in the box are used for screw fastening. From the factory, the double rocker is snapped onto the radio module. If it needs to be replaced with the large rocker, pull the rocker halves forward without bending them towards the center. Then snap the large rocker on so that its markings 0 and I on the back align with the radio module. When adhering, first attach the set of mounting plate with frame and mounting frame - with the snap-in parts at the top and bottom - then attach the set with the radio module and rocker.
