Arming Electronics?

[Missileman]

I am using 2 MAWD altimeters, both with their own battery.
Question is:
The electronics bay with the kit I am building came with a nifty key switch to arm the electronics. Problem is this switch is single pole. Can I arm both altimeters with this switch or do I need 2 seperate switchs?

I have always seen two switches. I think you'd prefer that to keep the redundancy factor alive.

You can do that. But as previously mentioned, it is nice to keep the redundancy factor in there if the switch gets jarred. Plus it is nice to listen to the continuity beeps from each altimeter seperate from each other.
