Touch-responsive indicator switch

摘要

In the touch-responsive indicator switch construction disclosed herein, an electrically energizable light source is viewable through a printed circuit contact assembly. In the contact assembly, an essentially transparent flexible polymer sheet is folded to provide three juxtaposed layers, a ring-shaped contact element on the top layer being deflectable through an aperture on the intermediate layer to make contact with a similar ring-shaped contact element on the bottom layer, the light source being viewable through the centers of the ring-shaped contact elements.
