I have been following this thread. I have one thing to input. ONLY use heavy duty switches. I used a push-button switch I bought from Apogee. It worked fine for my test launch and my L2 launch. But when I flew my rocket on the motor I designed it for, a 6 grain K motor, the switch cycled when the apogee (9800’) drogue deployment occurred. I lost contact with the TeleMetrum; and the rocket came down fast. It took 2 days and some help to find it. The rocket it took a year to build, was a total loss. TI think the TeleMetrum survived intact and fully functional. I will never use pushbutton switches again.

You are getting to practice with using your system before you really need it. When it does come down out of sight a mile away you'll be ready.

I guess next time I'll have to do it blind folded and tell everyone else to shut up ;-) Be careful what you wish for! The rocket gods have been known to "reward" such hubris with things like broken battery or switch wires at apogee...
