The CP Electronics MRT16 series of time delay switches are designed to provide timed control of lighting, heating or ventilation loads.
Please note: many of these items are no longer available at Sparks; see the full range of CP Electronics items here.
Using push button (the MRT16-PB), touch (light press required, the MRT16-WP), pull cord or remote activation(the MRT16-PC), the user can switch on a load for a preset time period and have the load turn off automatically after the time period has elapsed.
Multiple timing ranges come as standard to allow the time-out period to be set accurately. Time setting is achieved using switches and a thumbwheel at the rear of the unit.
As the CP Electronics MRT16PC timer has been designed for general-purpose loads, a Neutral feed is required at the switch position.
This will allow the timer to be used on various applications from incandescent, fluorescent and compact fluorescent lighting to heating and ventilation loads.
In particular, for the MRT16-PC time lag switch, this is a pull-cord activation switch with an optional external trigger.

The modes of operation selectable using the MRT16-PC pull-cord switch
- On/off: triggering the timer will turn on the load and start the timing. Triggering the timer again during timing will immediately turn off the load and stop the timing.
- Resetting: triggering the timer will turn on the load and start the timing. Triggering the timer again during timing will re-start the timing period from scratch. When using an external trigger In this mode, the timer will not start until the trigger is removed making it ideal for pump or fan overrun applications.
- Non-resetting: triggering the time will turn on the load and start the timing. Triggering the timer again during timing will have no effect.
