Abstract
A switch comprising two transistors connected in the form of a mixed Darlington circuit. The base of the second transistor is connected to the collector of a third transistor. The emitters of the first and third transistors are interconnected and the base of the third transistor is connected to the base of the third transistor, which is itself connected to the collector of the second transistor and to earth via a polarization resistor. An example of an integrated embodiment is disclosed.
