Stable, accurate and reliable twin switch unit that allows consecutive switching of two 240V outputs. So you can plug in two things and make them switch on consecutively.

1 to 60 minute setting on each output. 1100W maximum output - 3A each. When one finishes, the other starts. It is also possible to plug in only one and leave the other open so that one output runs for a period and then is off for a period.

Heaps of uses - not just an aquarium tool - use for switching on lamps while you are away on holiday etc. Useful for train sets, unmanned things that need to happen on a recurring basis etc.
