Using this red switch cover is easy. First, make sure you have a compatible toggle switch as the cover is for the switch only. To use the switch, simply flip up the red cover. You'll then have full access to the toggle switch beneath it. When you're done or want to quickly deactivate the switch, just push the cover down. It will force the switch arm back to the lower position, turning off the switch. As for maintenance, keep the cover clean by wiping it with a dry cloth. Avoid using harsh chemicals as they might damage the cover's color and material. And always double - check that the cover is properly closed to ensure the safety mechanism works as intended.
