As a total newbie, I'm just trying to put together a little percussion instrument, using 12v 'push' solenoids, but so far I've got a couple of the cheaper ones from Farnell and I'm not sure if they travel far enough when energised to be of use. Can anyone share advice on where to buy decent solenoids, please? I like the look of those Black Knight ones by PED, but they're also quite pricey, and possibly a little more powerful than necessary.
Also, I may as well get a stupid question out the way too. I got these solenoids as they were labelled as 'push', but I was under impression that the thick end of the rod was the 'front' of the solenoid, rather than the thin end. Unless I've been sold the wrong components, it would appear the thin end is actually the front (which shoots/pushes outwards when energised) -- is this correct? In which case the plunger will fall out if the solenoid's pointed upwards, which is less than optimal.
