The MSC-L is either a SPDT (L) or DPDT (L1) switch used for switching on or off speakers. There is also a DPDT center-off (L2) version that allows you to switch between speakers. The SPDT version is standard. The module mounts into a standard single-gang electrical box (not provided) and is finished off using a matching decora cover plate (see HPS-1). Connections on the sound system side of the switch are made via pigtail wires. Modules are available in Brown, Ivory or White.
