4-way RCA double switch board

This is a simple board with eight RCA connectors and a common screw terminal connector. These are two classic 1 to 4 switches. Switching by small relays.

This board can be used, for example, for switching Audio or PTT and ALC signals. The blue screw terminal connector is the common input/output of the middle of the switch for the upper and lower quad RCA connectors.

The board requires a power supply voltage of 8 to 20V AC or DC - 10 to 12V DC is recommended.

Switching is via positive voltage on pins 1 to 4. It is also possible to switch multiple ports at the same time! A simple rotary switch is sufficient for switching. A connecting flat cable (about 50 cm) between the board and the eventual switch is also included.
