Terminal convertible alternating current switch

摘要

An electronic A.C. switch which affords either "normally open" or "normally closed" type of operation to a connected alternating current source and load in accordance with which of two alternate terminals such source and load are connected in addition to a third common terminal. Its operation is automatically inhibited in the event the A.C. source and load are connected to both of such alternate terminals simultaneously. It can be used with a wide variety of electrical sensor devices for effecting its operation between either of its normal and opposite circuit states.
