It can be used as an off switch in a single-pole design or for controlling lighting systems. The switch is illuminated, allowing for easy identification in the dark. With the included label insert, it can also be configured as a heating emergency switch, providing additional safety. Installation is surface-mounted, and the terminal blocks facilitate the setup. The switch has an IP 44 protection rating, making it suitable for use in damp environments. Additionally, the front-side retrofitting of lighting modules allows for flexible adjustments without disassembling the switch. The front-accessible measurement and testing contacts also simplify maintenance and inspection.
