Do you have an ignition cut off (i.e. RCATS or Smart-FLy, etc) ?

If so, you can rid yourself of the problematic on/off switch on ignition. I hard wire my cut-off switch to the battery and directly to the ignition . When the RX is off, so is the cut off so the battery is out of the circuit. I have a 2-leaded battery made up (fromeco) - one lead is a standard JR charge lead and one is a 18 gauge pigtail that is wired into the cut-off relay.

I have not used ignition switches for a long time. Also - cut-offs will soon be mandatory for IMAC.
