I have been looking at switches... I really want something that is illumnated... Problem is... if you pass a full 12v for the light it is blinding. I wired up a varible resister as a test, and found that 4 volts was very comfortable. In these photos I am using my drill motor battery as a power supply, and you may recognize the mock up from the EAA Education Siminar... Electrical Class.
The Vertical Power VP-X Pro regulates the power, so the switch does not carry any load, so you can use pretty much any switch you want.
