Hi there! If you are referring to the Wemo Light Switch, try a reboot or a reset and see if the setback recurs. Make sure that there are no rules that were set and firmware is up to date. This might have something to do with how the wires have been connected. The tweaks done by other users and moderators on this related Community thread could help us isolate the setback: http://community.wemo.com/t5/WEMO-Hardware/Help-WeMo-light-switch-turns-off-immediately/td-p/27667.

I'd suggest caution here - it sounds like you've got wiring that was done after your home was built (since it's not using standard wires) and it may not be wired to code. Investing in a test meter would be wise. It would also be a good idea to check the fixture to see how it's been wired - hopefully that side has proper wiring - and this may clarify how the switch itself has been wired.
It does sound like the fixture may be wired with power passing through the load, on to the switch, then back to neutral at the fixture (which here anyway is not to code). This would both account for the switch rebooting when it switches (it loses voltage/power, opens the relay, and then goes back to having enough voltage to restart), and a weaker spark if you touch it to neutral (normally that should pop a fuse). One way to check is to remove the bulb from the fixture which should then interrupt power to the wemo completely.
Normally in a "power through fixture" circuit the power should be passed from line in (black) to the switch over a properly marked white, then back out of the switch to the fixture. Since you have neutral at your switch you *might* be able to fix this by sorting out the wiring on the fixture to pass hot directly to the switch. From there the wemo can be properly powered and the power switched to the fixture. It would be a *very* good idea to consult with an electrician.
