OG4318 - Wafer Switch Assemblies: Transmit/Receive Control Switch Assembly - Offering these unique pieces of hardware: Switching assemblies with indicator dial. The metal plate was obviously used in a transceiver, as it has two phenolic, rotary wafer switches: one is 4PDT. The other is a three-position switch; has dual wiper contacts, one of which opens in the T/R position of the shaft indicator, and connect in the R or OFF positions.
Bourns Rotary Encoder This 3-pin encoder produces a quadrature signal at the A and B channels to allow decoding of the rotational shaft movement. The internal detents are at 15 degree angles, for a total of 24 signals per revolution. There are no end-stops, so the encoder can be continuously rotated.
