Hi to all,
This is my first post on the site, although I have referenced it many times in the past.
I am trying to put together a circuit to control a pulse latching solenoid valve.
What the circuit needs to do:
When a tact button is pressed, it sends current to the solenoid valve to open the valve. When the button is pressed again, the polarity to the coil is reversed to close the valve.
I have looked at Sequential Switching Bistable Bultivibrators and have found several schematics but without instruction as to the resistor type (PNP/NPN).

I have successfully achieved this with an H-bridge circuit but I am having trouble integrating it into a push button system.
A schematic, link, or other instructions would be greatly appreciated.
