Switchy

Turn on and off three modules

Switchy is a module that allows you to turn on or off up to three modules (or busboard) independently of each other.
No need to turn off the whole case: All three voltages (+12V, -12V, 5V) are interrupted at the same time.
Used to reduce the background noise of certain "noisy" digital modules when not in use, to initialize certain modules or change their function, to change an SD card, to relieve the power supply with energy-consuming modules, etc.
