Finger activated switching device
Abstract:
A finger activated switching device has an enclosure with a top wall and a bottom wall, the bottom wall movable on a supporting wall. An upper lever is pivotally joined to the enclosure, and is upwardly spaced apart from the top wall in a first rest position yet is upwardly displaceable using finger pressure from below. A lower lever is pivotally joined to the enclosure directly below the upper lever, and spaced apart from it in a second rest position yet is downwardly displaceable using finger pressure. When the levers are displaced from their rest positions a restoring element moves the levers back to their rest positions. Switching elements positioned in force transmission mechanisms with the levers provide electrical switching actions when the levers are displaced.
