The magnetic switch is reliable and easy to use in any rocket installation without needing any exterior holes to be drilled or aligned.

• 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)
• Current capability of 20 Amps for one second, or 12 Amps continuously.
• 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.
• Small magnet Included.

​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.
