Hack local dimming for X10 wall switch

A very simple solder hack to implement local dimming with an X10 wall switch. The basic concept is that the X10 dimmers can dim the lights via software, but not via the actual switch itself. It takes one single solder short to implement this. Talk about easy if you’ve done any easy soldering before.
X10 is a technology that allows you to control your appliances and devices from the network/Internet.
