A-182-2 is a simple passive module that contains four changeover switches, which are used to connect or disconnect the sockets of the corresponding socket triplet:

• in the upper position of the switch the upper socket of the corresponding socket triplet is connected to the center socket 
• in the lower position of the switch the lower socket of the corresponding socket triplet is connected to the center socket 
• in the center position of the switch the sockets are not connected

Each unit of the module can be used to switch between two signals or to interrupt/connect a signal. In the last case the third socket of the triplet is not used.
The module is fully passive and both audio or control signals can be switched.
