Abstract
A monitored security switch assembly includes a switching system, a transmission line, and a monitoring system. The switching system has a load element. The security switch assembly uses an oscillatory voltage to determine if the monitoring system, the switching system and the transmission line are impedance matched. The security switch system can function in a transmission mode or a reflection mode.
