Hello, I'm trying to use 1 Feather Weight Magnetic switch to turn on 2 Easy Mini Altimeters. I don't want to run 2 magnetic switches for fear of not turning both on with the magnet pass, and/or turning one of them back off. Push button switches are not an option (as I'm installing the electronics tray up inside of a Loc 7..67 nose cone with limited space through the bottom hole. I tested running 1 altimeter with the magnetic switch (9v battery connected directly to the altimeter), (ground from 9V to ground on magnetic switch), (altimeter on switch to magnetic switch in), (altimeter switch on to magnetic switch out). A magnet pass was able to turn the altimeter on and off. However, my concern is can I run both EasyMIni switch outs to the same single Feather Weight magnetic switch (in/out)'s and not hurt/affect the performance of both altimeters. I checked the EasyMini schematic and it appears there is power interruption to activate the unit in the switch port. I'm just concerned about hooking both of those power interrupts via the Feather Weight switch to arm them. Should still be 9v parallel but double the amperage, correct? Any other concerns of both electronics firing with the battery draw? Or is the dual 9v sufficient? Really appreciate anyone's input with this arrangement.
