Hey everyone! I'm just getting my feet wet in virtual pinball and planning my first build. I've got soooo many questions, but let's start with contactors.

 

How do I know if a contactor I find online is 12v or 24v?

 

Here's an example:SIEMENS CONTACTORS 3RH1140-1AK60 and the datasheet: https://controlparts...0.datasheet.pdf

 

Are these appropriate for virtual pinball? What sort of power supply would they require?

Recommend that you start reading these guides : http://mjrnet.org/pinscape/

The datasheet is pretty clear that this is a contractor that needs AC voltage to turn it on. You need ones that are suitable for 24V DC. Look for a model number like this 3RT1016-1BB41. I think the 3RT1015 series are also 24V DC. Here are two fairly cheap to get you started. The tall thingy sticking up is a surge suppressor should save you needing a diode for the contactor.

 

And I second the recommendation for you should read MJR's build guide. It should answer a lot of your questions.

 

Shameless plug to you and other newbies: When you are ready you might want to look at some of the ready-built electronics that I offer which at least eliminates building stuff yourself. See the link in my signature below.

Thank you both, that's helpful.

So would something like a Siemens 3TF3000-0B (20 AMP 600 VOLT 24 VDC COIL CONTACTOR) work?

I sell "ThunderClap" contactors made for this on eBay, just search.  New product that is made for what you're trying to do.

 

Sorry for the plug but they are quite suitable.

Yes possibly.

 

The output current and voltage (20A 600V) is not so interesting per se. The real question is what kind of noise does it make and how loud. Some of this is trial and error. The other two model numbers I quoted are frequently used by hobbyists.
