Features:
Uses CMOS digital IC for oscillation and frequency division.
Stable, accurate and reliable!
Built in fuse to protect the switch and prevent output overload from damaging the fittings.
Circuit-A and Circuit-B operate alternately and the output times can be adjusted individually.
Each timer is set from 8 sec to 8 min

Usage example:
Preventing dead current areas in the tank – Connect one pump to Circuit A and set the timer for 5 minutes. Then connect a second pump in a different area to Circuit B pump and set the timer for 5 minutes. This simulates river and ocean currents. Pump A runs for 5 minutes then switches off and pump B turns on and runs for 5 minutes. The pumps alternate continuously.
The intermittent switch can also be used for lighting systems in aquariums with special corals to alternate between different coloured lights
