ABSTRACT:
A snap acting fiber optic switch in which a carrier operates between two stop surfaces separated by a wedge shaped gap. A planar shutter perpendicular to the stop surfaces extends from an end of the carrier at the wide end of the wedge shaped gap into a gap between opposing end faces of a pair of optical fibers aligned with an axis perpendicular to the plane of the shutter. A plunger actuated over center snap acting mechanism biases the carrier toward one or the other of the stop surfaces, depending on the position of the plunger.
