The Columbus 400A 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.

The Columbus 400 offers a variety of options for either installation or replacement of existing single gang switches for use on incandescent, fluorescent or compact fluorescent lighting applications.

Activating this pneumatic switch will turn on the lights for an adjustable length of time (between 10 seconds and 10 minutes). Very easy to install, this is an ideal replacement for an existing light switch.
