I am currently building a Rocket, and the altimeter location makes the little screw switches I normally use not practicle. I have been looking at reed sensors and latching reed sensors and was wondering about the posibilities of arming the altimeter through the rocket body with a magnet.
I am a bit concerned about the latching ones staying latched at mach 2 and the shock of flight and the ejection charges. And also getting one that would meet the specs of the altimeter.
If the altimeter turned off, in flight, that would be a real bad thing!

Its the HA45. (click on HIALT45K)
We normaly jump the switch block and then switch the battery leads instead for safety.
When the electric match fires it draws 5 amps from the 9 volt battery. The sensors I have seen so far dont seam to be rated that high. ??? May be a combination of a reed sensor and latching relay. Any help would be greatly apreciated, schematics, part numbers.
I know how to solder, but my electronic knowlage is limited. I have built circuit boards in the past, but I had plans and part numbers.
