Introduction to the Common Function Buttons on Electric Wheelchair Controllers

The functionality of the buttons on an electric wheelchair controller can vary depending on the brand and model. Taking the Topmedi brand of electric wheelchairs as an example, the controller typically features the following basic function buttons or control mechanisms:

1. Power Switch: This switch is used to turn on or off the power of the electric wheelchair.

2. Speed Adjustment Button/Dial: Adjusting this button or dial allows the user to change the speed of the wheelchair according to their needs and the safety of their environment.

3. Battery Level Indicator: This feature displays the remaining battery life of the wheelchair.

4. Sound Button (Horn): This button can produce an alert sound or other noises to draw the attention of pedestrians or vehicles in case of emergencies.

5. Joystick: Serving as the primary control input device, the joystick is used to steer the wheelchair, enabling movement in forward, reverse, and side-to-side directions.
