I have a 12v electric ball valve (3 wire) and a 12v 2 wire inflation pump which I am using for a project. I need the ball valve to open then close after 10 seconds and the inflation pump to run for 12 seconds simultaneously. I have managed to achieve this using 2x12v timer switches which I purchased off ebay (link below) . The problem is I need a second button/switch to press that will deflate by opening the ball valve then close it 20 seconds after, I thought this would be achievable by introducing a third timer switch and a simple on/off/on switch, I wired the first two timer switches to the first 'on' then the single timer switch to the second switch but they all seem to interfere with each other and when I want to power the single one they all light up.

Hope someone can please help as I haven't got a clue when it comes to electrics or anything for that matter.
