Installation Steps:

- Powering On: Once the switch is properly installed and the ESC is connected to a battery, move the toggle lever to the 'ON' position. Your ESC should power up, indicated by LED lights or an audible tone, depending on your ESC model.
- Powering Off: To turn off your ESC, move the toggle lever to the 'OFF' position. The ESC should power down.
- Always Disconnect Battery: For long-term storage or when performing maintenance, always disconnect the battery from the ESC, even if the power switch is in the 'OFF' position.
