The TDS3-L time delay switch with LED indicator provides timed control for lighting, heating and ventilation loads. They are simple to install and easy to operate.  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 20mm.

The time delay switches are very easy to use; touching the touch-sensitive button with a finger 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 momentarily holding their finger on the button. The time delay can be adjusted via an internal thumbwheel from 6 seconds to 60 minutes.

The TDS3-L is supplied with an illuminated touch-sensitive pushbutton to ensure that they are easily located in the dark. The LED will turn off once the load has been switched on.
