I am making a pool ioniser. It is powered from a Polycrystalline silicon solar panel.

Optimum operating voltage is 6 Volts and the optimum operating current is 0.05 amps.

The circuit supplies 2 copper electrodes. I want to make them alternate every hour and was using a double pole double toggle relay wired as per attached drawing.

I have a PIC10F200 which I can get it to toggle the output. I just don't know how or what I could uses in place of the relay.

Any assistance will be greatly appreciated

 

The relay you attached should work fine. Why are you trying to find a substitute?
If you do use a relay, be sure the include a subbing diode across the relay coil to prevent damage to the output of your PIC.

 

An h bridge should work as a substitute.

The relay however will not work as shown, as when NO. contacts close, it connects + to -.

 

You got your criss-cross in the wrong place.
