Hey
I am trying to build a very simple circuit that will switch on and off four solenoid valves. The valves that I am using can be found at the following link

I thought it would be as simple as running a 24V supply, with each solenoid connected in parallel, and each solenoid connected to a switch, so each one can be switched individually. Also there is a diode connected in parallel around each solenoid to deal with the negative emf that can be generated. But this circuit doesn't want to work! Doesn't seem as simple as what I have first thought.
I did electronics 7 years ago, and now have forgotten everything. So I really need some help! So could someone help me with a circuit design that will enable me to turn each solenoid on and off individually. I know it must be something simple which I have missed.
Thanks
Jay
