Electric Push Button
Prior to the toggle switch a popular design was the push-button switch, composed of a depressed button oriented below or beside a raised button. Pushing the raised button opens or closes the contacts while popping out the previously depressed button so the process can be reversed. Push button switch reproductions are available on the market today for vintage or authentic styling.
