The Liga Swisspir motion sensor 12–24V in black is a compact PIR motion sensor for automatic switching of low-voltage LED lighting, where connected 12V or 24V DC luminaires switch on when movement is detected and switch off after an adjustable delay time, making it suitable for applications such as LED strips, cabinet lighting and stair lighting where automatic control, energy saving and discreet installation are required, while the black finish allows seamless integration into dark or modern interiors.
