Abstract
A switch circuit is disclosed which both sets the voltage at an output terminal and signals that the voltage has been set. The switch circuit may be implemented with a single-pole single-throw switch. A voltage drop device, connected in parallel with the switch, is used to generate the output voltage levels. The switch circuit is also suitable for enabling and disabling the heartbeat signal generated by a local area network transceiver and for signaling whether the heartbeat signal has been enabled by lighting a light-emitting diode.
