Quote:Now that I'm thinking about it, a DPDT momentary toggle switch might make the most sense paired with a master key switch on the 120v line (1). Something like this perhaps...http://www.surpluscenter.com/item.asp?item=11-3259&catname=electricShould be easy to mount in a standard wall box and I can get one of those fancy switch covers to prevent accidental bumping.
Quote:Perhaps a couple of these for the limit switches?http://www.digikey.com/product-detail/en/V15T16-CZ100A05-K/480-2989-ND/1823501Or do I leave the existing limit switch in place and just add my own for the opposite direction?

Quote:Ok, so I think I've worked out a possible setup for my roof motor. I did a bit of editing to the schematic. Let me know if you think I may have mucked things up
Quote:Everything looks good except the power indicator lamp. You'll need to run the neutral side back over to line 3. As is, you'll be drawing power through the cap and motor windings to try to light it, and assuming it lit at all, it will do interesting things when you actually engage the motor! Depending on what you find for a keyed switch, you might actually go with a DPDT that can disconnect both the line and neutral of the whole setup, similar to just unplugging the hoist. Either way, I'd just bring the Romex into the box with your switches, catch your line and neutral there for the light, and then route them to the motor from there as needed. Thus 1 & 12 on the terminal block would go completely away and you'd just use 3, 7, 10, and 11 coming from your control box and limits. Don't forget your ground line though! Beo
Quote:Thanks Chris. Just curious why you chose that particular switch. I'm obviously new to this kind of thing and I love to know what the reasoning behind it is.
Quote:Sorry I didn't see your question sooner. I have been busy preparing to run a bunch of new fiber-optic cables from the focal plane of the UH88 telescope to the comm room below their control room. The cable route is a real maze of cable corridors and plenum spaces and everything must be pre-planned down to the small details.

Anyway, that's what I was figuring the reason was, but wanted to make sure. Given that I'd like to not have to mess with this once it's all wired up, that's probably the way I'll go.Thanks again.
