Standby Telemetry Transmitter Switch

In case of real-time or delay-time telemetry transmitter failure, the astronauts manually moves this switch to transmit vital spacecraft system parameters to the ground stations in real time or delayed time. It provides an alternate radio frequency (rf) link from the spacecraft to ground communication facilities for transmission of various data obtained by the Instrumentation System.
