The PCTDS3 Pull Cord Time Delay Switch provide timed control for lighting, heating and ventilation loads in areas where standard electrical switches are not allowed. They are simple to install and easy to use.  The 3-wire switch requires a Neutral and Live connection (but does not require a minimum load to be connected) and can be used either to replace an existing light switch, or on new installations.  The unit will fit into all British Standard single-gang pattress boxes with a minimum depth of 30mm.

The time delay switches are very easy to use; pulling on the cord will turn on the connected load. The load will be automatically switched off after the pre-selected delay has elapsed, or after the user cancels the function by pulling and holding the cord momentarily. The time delay can be adjusted via an internal thumbwheel from 6 seconds to 60 minutes.  Other time delay periods are available upon request at time of purchase (3 seconds to 30 minutes, 12 seconds to 120 minutes).

A 2-wire version of the PCTDS is also available:
PCTDS2: 2-wire version (Live In, Live Out), no neutral wire needed. Please note a minimum load of 40W is required. Power factor correction capacitors may be required for compact fluorescent installations.
