Staircase timer – reliable lighting control

This compact ASO-205 staircase timer is an ideal solution for controlling lighting in corridors, stairwells, basements or garages. The device automatically keeps the light on for a set time after pressing a momentary switch (bell button), and then turns it off automatically, providing comfort and energy savings. Mounting in a flush-mount box with a diameter of 60 mm makes it discreet and easy to install.

Functionality and application

The timer is designed to work with momentary switches, which means that after briefly pressing the button, the light remains on for the set time. After it expires, it turns off automatically. The lighting time is adjusted using a knob, allowing you to adapt the device's operation to individual needs – the adjustment range is from 0.5 to 10 minutes. The ability to work with backlit switches further increases user comfort.

The device is perfect for both residential and commercial buildings. Thanks to its compact size and the possibility of mounting in a standard flush-mount box, installation is simple and does not require complicated modifications to the existing electrical installation.
