The Main Switch, also known as the 'Power button' (ON/OFF) for Dualtron, is situated within the left plastic deck side cover of the scooter body. Starting from January 2020, Minimotors has transitioned to using smaller connectors compared to previous versions. If your scooter has larger connectors, simply replace them with the provided connectors to ensure compatibility. This Main Switch is designed specifically for the Dualtron Achilleus model and includes 1x main switch with cables, making it an original Minimotors item.
