Eltako wireless switch, 80x80mm exterior, frame inner dimensions 55x55mm, 15mm high. Generates energy for radio telegrams even when the button is pressed, thus no connection cable and no standby loss. With a single rocker and double rocker. Smart Home sensor. The package includes the frame R, a 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. Wireless switches with a single rocker can send two evaluable signals, while those with a double rocker can send four. The mounting plate can be screwed onto a flat surface or glued 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. The double rocker is factory-installed on 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 in place so that its markings 0 and I on the back align with the radio module. When gluing, first attach the mounting plate set with frame and mounting frame - with the latches at the top and bottom - then attach the radio module set with rocker.
