Narrow Blinds Switch 3 Positions SIMON 270 allows to control the position we want to have in every moment, without the need to maintain the switch pressed. The mechanism needs to be completed on the metal base frame and then install the minimal frame (not included) obtaining a robust set of minimalist and elegant aesthetics. For its connection 3 wires are needed, power, up and down, which are installed by means of the quick clamps of pressure and easy to identify. Reference: 20001333
