relay to control line voltage device with low voltage switch?
james
switch low voltage device. So I need to add a relay in-between.
Is there any pre-packaged relay that includes a low voltage output (that can
be used to power the relay), a 3-prong power cord, and a 3-prong outlet?
I found something called "honeywell switching relay" that seems close to
what I need but doesn't have a power cord or a 3-prong outlet. Although I
can wire those items myself, I prefer a unit that comes with them. Any
suggestions?

I'm not 100% certain from your post exactly
what you want. There are plenty of pre-packaged
switching devices on the market. Two well-known
brands are ELK Products and Altronix.
If you can be more specific perhaps I or some of
the others here can offer some advice.
Will your device need to switch the appliance on
when there is a low voltage input, a high voltage
input, or both?
Will the appliance then be switched off upon loss
of the low voltage inut (obvioulsly if the high-voltage
goes the appliance stops, too)?
Following are examples of low-voltage switching
boards from ELK Products and Altronix. I no longer
carry ELK Products. I do sell Altronix so I might
tend to have a bias, but the only issue for you is
what will do the job.
ELK Products (competitor's website):

http://www.smarthomeusa.com/ShopByManufacturer/ELK-Products/Item/ELK-912B/
To the best of my knowledge Smarthome is an
honest company but they're my competition so
of course I hope you'll look at our offering as well.
Altronix (my website):

I carry the entire Altronix line. I haven't finished
entering the descriptions so here are links to Altronix
for a more complete description:

Hope that helps.

You don't explain what you're going to use for controlling the relay. What
sort of appliance is on the switched AC circuit? Some handle control like
this better than others, some not very well at all.
Russound and Niles also make controllable AC outlet switches. They
typically use a 12v signal to control the AC outlet. I've got a Russound
unit that controls an amp for outside speakers. The control system closes
the DC circuit and activates the AC outlet.
Given the risks associated with 120vac it would probably be a good idea to
use an off-the-shelf, UL listed sort of device.

Might be worthwhile to find or figure the current needed, too. Switching
a quarter amp is a WHOLE bunch different that switching 25A :-)

OK, that's relatively easy.

Not in general, no. 'low voltage device' can mean ANYTHING, Do you
mean some logic system with 5V power? Some kind of switch that
will blow up if there's a spark? A gizmo that might touch wet skin,
and that must be grounded for safety? Is it the wire connecting to
the
relay required to have some specific voltage limits?
My finger flicking a light switch is an input, and it qualifies as low
voltage if I haven't shuffled on the carpet...
