All,

I am changing out the switch and my stick grip from a toggle type switch that is used with the infinity stick grips. The switch is currently a three position toggle switch with an on off momentary on positions.

I would like to wire in a simple pushbutton switch. The pushbutton switches that infinity arrow uses have three terminals on them. And I wanted to know if anybody had done this and how they did it? In other words, how did you wire each terminal on the switch?

@George Wehrung, I'd give JD at Infinity a call any time after 1300 Pacific time as he's a night owl. He's been very helpful during the order/build for mine.

I talk to him last night, but he didn’t know which switch they needed

So thanks to Paul’s advice; I went with the infinityaerospace 8636 switch and as Jon mentions it’s a push on push off. I wired power to the center terminal on the switch and the up and down wires at the outer two.

I decided to use the toggle switch for the flaps. It will be center off, momentary down for extension and up for retract. I haven’t decided which side I prefer the flap and speed brakes on but likely it will be the outer side as it always gets hit when people are getting in and out. I also like the toggle up so the flaps will retract without me having to hold the switch. I am thinking for a go around scenario.
