ABSTRACT:
A telecommunication instrument having a microphone mounted in a flip arm is electrically interconnected to the transceiver portion of the instrument by a slip ring connection. The slip ring connection enables the flip arm to be rotated between stored and operating positions during use, and easily removed from the instrument for repair or replacement. The slip ring connection eliminates any need for extending wires or flexible circuits between the flip arm and the main body of the instrument.
