Toggle Light Switch

As you’ve read earlier, this is the electrical device invented by Newton more than 100 years ago. And not surprisingly, it is the type of light switch that is most commonly found in homes across the world. You likely have one in your room right now.

The toggle light switch is a simple electrical device that’s still used more than a century after it was invented. It is also easy to use: you simply flip the toggle switch up to switch on the lights and flip it back down to switch off. This is a light switch that would work well for any general lighting purpose.

The push-button light switch has two buttons. One closes the contacts while the other opens them. When you push the raised button, it opens or closes the contacts and causes the previously depressed button to pop out, allowing the process to be reversed. The buttons are commonly colored black in the U.S., with the ‘on’ button colored white to indicate its function. Many push-button light switches are still available these days for vintage styling.
