| Dec 26, 2019 at 20:28 | comment | added | jsotola | think of a SPST switch ... one terminal is connected to ground ... the other terminal is connected to the output ... closing the switch connects the output to ground ... opening the switch disconnects the output from ground and allows the output to "float" | |
