So how would I use this if I have two LEDwiz's and want my coin doors lit?  I just might be stupid.

What voltage are your coin door lights, and do you want them controlled by the led wiz? (or just on all the time)

No idea about the voltage, I haven't got that far yet.   I would want them on all the time though.

As an example, on occassion I need to reboot my cable modem (much less often now that I replaced it) and sometimes my router.  Using this and a driver app, I could power cycle my modem?  (Sample app would ping my webhost every x minutes and after two consecutive failures, it would send a trigger to the parallel port to trigger the relay, first off, then on).  Is that the concept?

Yes, you've got the idea.  Theres lots of neat stuff you can do with the parallel port and a relay or two.

With the "LO" version, can a dedicated microswitch be wired just to the powermite (bypassing a keyboard encoder)?

Thanks.

You can use LO or HI for this.  For LO connect to ground, for HI connect to 5v.
EDIT:  Of course with a momentary type button you would have to keep pressing the button to keep the relay energized.  An on/off type switch would work though.

For a momentary type button, if it was wired NC instead of NO, (I think all microswitches I have that came with buttons have this option), then pressing the button would break the connection until release.

Excuse my ignorance here on relays.  Would it be possible to wire this up so the relay is NC and the trigger breaks the connection until trigger power drops? (thinking from the parallel port trigger perspective)

What is the lifespan of one of these relays if in a "constant on" state?  Or does that not really effect the lifespan?

Next trick is to convince the Mrs that I wouldn't burn down the house if I got one of these.

Sounds like your best bet then would be to use LEDs, with the proper resister, to lite the coin door.  Then you can get the power either directly from the LEDWiz (only one needed) or from the 5v terminals on the Powermite.  You can also get your external 5v supply for the LEDWiz from the Powermite.

Yes, the Relay also has a terminal position for NC (normally closed) so energizing the relay could break the contact.

Relays lifespan is usually measured in operations...how many times it is switched.  Under no load it is rated for 1million and under a full load of 12 amps it is rated for 100,000.  So for what any of us would likely be using this for, it will last for years and years (and years)
