Wireless button, 80x80mm outside, frame inner dimensions 55x55mm, 15mm high. Generates the energy for radio telegrams even when the button is pressed, therefore no connection cable and no standby loss. With rocker and double rocker. Smart home sensor. The scope of delivery includes the R frame, a W55 rocker, a DW55 double rocker (all the same color), a BRF mounting frame, the HP holding plate, the radio module and an adhesive film. Radio buttons with one rocker can send two evaluable signals, radio buttons with double rockers can send four. The holding plate can be screwed onto a flat surface or stuck to the wall, glass or furniture with the included adhesive film. The sleeves in the box are used for screw fastening over a 55mm switch box. The double rocker is snapped onto the radio module at the factory. If you want to replace it with the large rocker, pull the rocker halves forwards and do not bend them towards the middle. Then snap the large rocker on so that the markings 0 and I on the back match the radio module. When gluing it on, first glue the set of holding plate with frame and fastening frame - with the notches at the top and bottom. Then snap the radio module set into place with the rocker switch - marking 0 on the back is always at the top.
