I am interested in this one as well having just wired my starter switch, exactly the same set up as Jeff in the above post except I used the strobe circuit to enable the start button.

Dave,
Can you give me any guidance on how to set that up?

I thought about doing something like this, but should the switch in the baggage compartment fail inflight and you subsequently had an engine failure, the engine would not start. Hence, I'm trying to find a way to balance safety yet keep the start sequence simple. I'm not throwing stones at anyone who has done this, simply trying to figure this out!

I do push button start switches on 90% of my panel installs, on a few occasions customers wanted a way to kill the start circuit so I will mount the start CB on the lower bent edge of the panel or somewhere out of the way but easily reachable, so the breaker can be pulled to disable the system if desired.

Just use a key-switch to control the master contactor.
The 1st example that popped up:

Just realize that in most cases, when teh engine quits, the poropellor keeps windmilling - you have to fly very, very slowly (and intentionally) to get it to stop. Bottom line - you donít need a starter to restart in the air. Just restore fuel and/or spark.

Just to add to what Ironflight says, If the failure is such that the prop isn't windmilling, you probably shouldn't use the starter anyway.

I too am thinking of a push button start switch.

My concerns are not accidentally hitting the starter or a stolen airplane. No, My concern is leaving the mags hot while I'm outside the airplane.

For over 40 years, when I'm not in the airplane (ie preflight), if I'm going to touch the propeller, I look up to see if the keys are on the glare shield. If not, I check the mag switch and/or check my pockets for the keys. I haven't got beyond how to remedy that with a keyless system except maybe with dual P-mags that's not an issue.

I use a push button starter and two switches for the two mags. The right mag has a double pole double throw switch, If the switch is off, then the P lead is not grounded and the starter solenoid is not powered. If the switch is on, then the P lead is grounded and the starter solenoid is live, just waiting for the button to be pushed. Works well and starting I turn R mag off, press the button and when it fires turn the right mag on, which kills power to the start button.
