Does that mean I need a DPST switch? I think the extra two terminals on the original switch allow the tv to have its instant on feature.
The terminals are labeled as follows, starting with the green lead, counterclockwise:
Green Lead=D
Red Lead=F
Black Lead=C
Jumpered Lead from Green terminal=A

It is the 115 ohm in parallel with the switch that enables the instant on. I personally don't like instant on as it can wear out the tubes... what I would do is snip out that 115 ohm resistor and bridge the fusistor terminal over to the heater terminal of the switch.... another option that would prevent changing the control and also prevent switch wear is to have the good section of the switch drive a the coil of a 120VAC coil DPST (or a correctly wired DPDT) relay.
