Pneumatic timer

The Columbus®timer is an easy to fit and cost effective way of automatically turning lighting off after a set period of time. Pushing the button switches the contacts and activates the time delay, which can be set at installation anywhere between 10 seconds and 10 minutes.
The unit has normally open or change over contacts as standard and can be fitted to existing single gang switches, making it a perfect low cost energy saving solution in areas such as stairways and storerooms.
