The desired brightness can be set using the slider; the device is switched on and off at the separate switch without changing the set brightness. The orientation light on the device makes it easier to find the device even in the dark. With the various connection options, the cord dimmer can be used alternatively as an intermediate or terminal device. The device has a built-in fine-wire fuse, which can be easily changed by the user if required. Suitable for lamps with protective conductor connection.
