Connecting a Control Input
You can connect to the control terminals to enable the Garmin PowerSwitch device to turn on customizable
outputs. For example, you can connect your vehicle ignition switch to a control input terminal to turn on
accessories automatically each time you start your vehicle. The control terminals detect a signal from 3.3 V to
18 V. You can configure output functions with the Garmin PowerSwitch app.
Connect the control wire from the control source in your vehicle to one of the two control terminals on the
Garmin PowerSwitch device.
