LogicSwitch is a small circuit that originally came from the idea of shutting down Optipower Ultra Guard from transmitter instead of reaching for the small button in inconveniently placed Ultra Guard. Read the original solution here and a how-to from here.
The manufactured version is smaller and has an added 0Ω output to go with the original 100Ω current protected output.

Examples of use:

Shutdown of UltraGuard
Smoke launcher with LogicSwitch
