I hoping to find about a half dozen coin mechanisms that would take a dime or quarter and engage a set of low voltage (25v max) relays for about two minutes. They don't have to be new or fancy, and they sure as heck don't need casino-grade counterfit protection. Shape/style isn't an issue as I will be designing the case. Anyone have any thoughts or sources?

Modified pinball machine mech maybe? Creighton

Tim,
If I'm understanding you correctly, you need the coil voltage on the relays to be 25 volts...? I think 24v will be readily available; however, remember that most electric coin mechs use 110v to activate the electro-magnet. I have quite a few 4 pole relays for various coil voltages and only a few timer relays that may even be 110v DC coils but I think these are time delayed on meaning the timing controls the duration before it pulls the contacts. I think you are looking to pull the contacts for a certain period (2 minutes) and then release the contacts... I don't have my reference books at my disposal right now, but I suggest looking in Grainger...
May I ask what you're building... '>

oh, yeah, that would probably make more sense consideing I have no idea what happens on the back of any coin mechanism.
I want a kid to deposit a quarter and make a toy train run around for a while. The trains run on roughly 18 volts.
I guess I was hoping to put something like this http://tinyurl.com/85k23 into the side of the layout.
Likewise, I have a couple of animated things like a carousel on the train layout which I'd like to have a kid deposit a dime or quarter to make operate for a little while. Same voltage level.
of course, now that you know my secret....

interesting idea. I'd asume that this set would be under glass or somehow protected from little (or big '> ) hands?

Tim,
The 18 volts is your operating voltage for the train/accessories so then you really don't need to have an eighteen volt coil for the relay because the relay contacts are actually going to complete your circuit... I looked in Grainger and found Relay Timers in on pages 452-454 of catalog #394(2004). There is a description of each delay type which can get a little confusing...
One thing to remember with regards to relays is that the circuit voltage for the relay coil and circuit voltage passing through the contact(s) doesn't have to be the same and in most cases, it isn't. In your case, you'll be utilizing a 120 volt circuit(coin mech) to control an 18 volt circuit via the relay contact(s). If you obtain a multi-contact relay, commonly called 2 pole or 4 pole(DPDT, 4PDT or SPDT(Single Pole Double Throw)), you can control various voltage schemes from one relay. Ex: Suppose your train operates at 18v, all lighting is 120v and a possible extra piece of equipment is 12v dc, a 4 pole relay can accomodate this with 120v relay coil that is activated from your coin mech...
Hopefully a little helpful...

Yep.. I do want to operate off the relay contacts. Part that's confusing me or that I know least about is what is on the 'back' of any coin mechanism. For instance I didn't realize that they need 110v I thought they just mechanically closed a switch or something. I hate working with 110v and will do a lot to avoid it. Might come in handy for keeping the kids off the trains, tho.
