This electronic relay has 2 independent channels. Each output can drive 70 Watt. The small size allows installation in the handlebar or headlight. You can switch different loads with one push button. Two different inputs allow you to control each output with the pushbutton, whether the pushbutton is wired to ground or + 12V. The Touch 2 Switch module can also be used as a standard toggle switch relay. Just connect the thin brown input cable directly to ground and the thin blue input cable directly to + 12 volts. That's it. Now the module switches between output 1 and output 2 when you press the button wired to the thin purple cable.
