With a 4 foot span, my arms aren't long enough to reach that from both sides.
If I want the outside switch to be disabled, that's easy to do with a simple switch on the inside.
My goal is to have the two switches, one on each side. They'll actually trigger relays in a control box that actually controls the liftgate. There will be an interlock so that when one relay is activated, the other one is locked out to avoid the dreaded short circuit with opposing switches.
John- what about a simple set of 3-way switches to control power to the lift gate? One switch on each side in a discrete location would send power to the controller. Once the gate is moved you can flip the switch on the other side and kill power to the controls. Add a pilot light at each switch location to confirm if power is on or off. Here is a basic 3-way schematic. Several other options here.
As the guru of all things electronic, I'm sure you have a great control system planned but I'm a firm believer in the KISS method.
