[[File:Push Button Light Switch.jpg|thumb|Vintage push-button light switches]]

The [[push-button]] light switch has two buttons: one that closes the contacts and one that opens the contacts. Pushing the raised button opens or closes the contacts and pops out the previously depressed button so the process can be reversed.  In the U.S., the buttons were commonly black; the "on" button typically had a white mother-of-pearl (real or simulated) inlay to indicate its function.  By convention, the switch was customarily installed with the "on" button on top.  Push-button switch reproductions are available on the market today for vintage or authentic styling.
