Abstract
A contactless relay wherein the application of an A.C. signal to the primary winding of a transformer is controlled by a command input, and the A.C. signal obtained from the secondary winding of the transformer is rectified into a D.C. signal by a rectifier circuit. The D.C. signal drives a transistor switching element for switching action. The switching element includes a single bipolar transistor, or a pair of bipolar transistors which can be connected in parallel to increase the current-carrying capacity of the relay. The output terminals of the relay can be rendered non-polar by constructing the relay of two bipolar transistors having commonly connected emitters and commonly connected bases.
