yuandrew's video: Leviton silent mercury light switch

@Leviton silent mercury light switch
This is a light switch which uses a mercury filled tilt switch to complete the circuit when the toggle is flipped upward. Sold in the past as silent light switches as they do not "click" or make any noise when operated. Popular from the mid 60's to the late 70's, environmental concerns about the effects of mercury have since put an end to the manufacturer and sale of these switches. Many still remain in service.
