Columbus Pneumatic Timer Single Contact

The Columbus 400A Pneumatic Timer provides an easy-to-fit, cost-effective solution for automatically switching lighting off after a pre-set delay. It is designed for straightforward installation, replacing an existing single-gang wall switch without the need for a neutral wire, simplifying retrofits in many lighting circuits.

This versatile timer can be used in both AC and DC circuits and also functions as a voltage-free contacts timer, offering flexibility for various control applications. The adjustable activation time can be set from a brief 5 seconds up to 5 minutes, allowing you to tailor the delay to the specific requirements of the space, such as corridors, stairwells, or storage areas.
