Featherweight PCB Screw Switch

Ultra reliable and of course, ultra-small.  These screw switches are unique in that the underside of the screw head makes a reliable, preloaded contact to complete your circuit when it is snugged down.

Airstart safety switch:
These switches are great for adding another series switch to airstart ignitors for an additional layer of safety.  In that application, close the switch when the rocket is vertical, after the electronics are working and the deployment charges are armed.  The Raven will beep out the change in arm status for the airstart ignitors.
