Wireless 4-channel switch 55x55mm for Busch Reflex and Duro frames. It generates energy for wireless signals even when pressed, therefore it requires no connection wires and has no standby loss. Comes with a single rocker and a double rocker. Included in the package are one rocker, one double rocker, a mounting frame, a mounting plate (all in the same color), the wireless module, and an adhesive film. The wireless switch with a single rocker can send two actionable signals: pressing the top rocker and pressing the bottom rocker. The wireless switch with a double rocker can send four actionable signals: pressing two rockers at the top and bottom. 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 mounting. The double rocker is factory-mounted onto the wireless 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 into place so that its markings 0 and I on the back align with the wireless module. When adhering, first attach the mounting plate set with frame and mounting frame - with the latches at the top and bottom - to the surface. Then snap the wireless module set with rocker - marking 0 on the back always at the top - into place. Before screwing, detach the frame with the mounting frame from the mounting plate. To do this, push the latches of the mounting plate outward. Then screw the mounting plate - with the latches at the top and bottom - into place, snap the frame with the mounting frame into position, and snap the wireless module set with rocker - marking 0 on the back always at the top - into place. For screw mounting, we recommend sheet metal countersunk screws 2.9x25mm, DIN 7982 C. Suitable for both dowels 5x25mm and 55mm switch boxes.
