Abstract
A high-isolation call cord switch includes connectivity for a standard hospital-style push-button call cord while using low voltage alternating current to isolate detection circuitry from static electricity. An alternating current signal is used to permit transformer coupling, with its intrinsic isolation capability, between the call cord switch and the detection circuit.
