NOTE: THE TWO LEDS CAN BE CONNECTED VIA A SINGLE RESISTOR RATHER THAN TWO SEPARATE RESISTORS
PLEASE READ IMPORTANT INFORMATION ABOUT THE RELAY CONNECTIONS BELOW
A follow up to the Kato Unitrack Operation using Toggle and Pushbutton Switches video.
In this video we remove the pushbutton, replace the toggle switch with a momentary toggle switch and add some extra circuitry so that we can add some indicator LEDs.
