Where is the ETC device switch located?

ETC device switch is located on the top of the ETC electronic tag. ETC is an electronic toll collection system, also known as an automatic road payment system. It is a specialized road toll method used for toll roads, commonly found on highways, bridges or tunnels with toll policies, and certain sections of urban centers to alleviate traffic congestion. The installation method for the ETC device is as follows: 1. Purchase the ETC device, check if all components are complete, and review the installation manual; 2. Determine the installation direction of the ETC device, with the solar panel facing outward; 3. Peel off the adhesive backing of the device, fold the solar panel against the vehicle's front windshield, and press firmly to ensure secure adhesion; 4. Install the device on the upper center of the vehicle's front windshield without obstructing normal driving visibility. It should be adhered in one go and not removed for reapplication; 5. Insert the ETC card to activate the device. Upon hearing a beep and seeing the device indicator light up, the device is activated, and the installation is complete.
I see some people always asking where the switch is on that little ETC box. Having driven for almost twenty years, let me tell you, it doesn’t have a switch at all. This small device is usually installed on your car’s windshield, near the rearview mirror. It automatically turns on and starts working as soon as the car is started because it’s connected to the vehicle’s power supply. If it doesn’t respond, it might be a battery issue (some rely on built-in batteries) or a loose installation. I once encountered this on a long-distance trip—I pulled over to check if the device had fallen off, and when it hadn’t, I continued on my way. I recommend checking the indicator light monthly and testing it once before hitting the highway to avoid getting stuck at the toll booth, which can be incredibly frustrating. Safety first, after all.
ETC devices are actually quite smart. Having played with many new car accessories, they generally don't have a separate power switch. They're designed to activate automatically: they power on when the car starts. If you're looking for a button, newer models might have a small reset button on the side for re-pairing or testing. The device is usually positioned in the center of the windshield without obstructing the view. Some now even connect to mobile apps via Bluetooth after startup for easier toll card management. No manual switching is needed in daily use, reducing operational hassle. Just remember the battery lifespan - it might drain if the car isn't driven for extended periods. Don't worry too much though, just starting the car will take care of it.
