Magnetic Switch: ($25)
-Flexible input voltage range of 2.9 to 16 V
-Low quiescent current draw of under 3 micro-Amps. This switch can be left in standby for over a week without significantly draining even a tiny 135 mAhr lithium polymer battery.
-100% solid-state surface-mount components, professionally assembled in the USA
-The output power state is indicated by a blue LED
-Each switch is individually tested.
Just connect the battery to the + and Ground terminals, and connect the altimeter power to the output terminal. The switch is fun to turn on and off even when it’s not arming a rocket, working with a wave of a magnet as if by magic.
Available in the Featherweight Store for $25 with a standard magnet
- The magnetic switch is reliable and easy to use in any rocket installation without needing any exterior holes to be drilled or aligned.
- Features:
- -3 combination mounting holes and wire terminals, with built-in solder holes for flexible, easy installation
- -On/Off activation range of 1” with a small rare-earth magnet (included)
- -Small footprint of 0.75” x 0.55” (1.4 cm x 1.9 cm)
-Flexible input voltage range of 2.9 to 16 V
-Low quiescent current draw of under 3 micro-Amps. This switch can be left in standby for over a week without significantly draining even a tiny 135 mAhr lithium polymer battery.

Screw Switches ($5)
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 igniters 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 igniters.

Battery Charger ($17)
This charger is similar to the charger that is built-in to the 38mm Av-Bay active bulkhead, but in a stand-alone version that can be used to charge the battery for a 24mm or 29mm Av-Bay. Charge your Featherweight Av-bay battery with a simple USB-mini connection. This is the same standard USB connector found on almost all cameras and many cell phones. Includes 2-color charging LEDs to indicate when charger has USB power and when the battery is fully charged.

- Stand-alone USB battery charger for use with the 24mm and 29mm av-bays.
- A much larger magnet, capable of 2" arming range
- Each of the kit components are also available separately.
