The PVCS2 is an in-wall A/B speaker selector switch that installs in a junction box, just like a light switch. This switch makes it simple and easy to direct your home amplifier’s audio to two sets of speakers, such as one set indoors and one set outdoors. Activate the A speakers, B speakers, or both! Easy push button operation makes operation a breeze. The included Decora-style wall plate means this switch will unobtrusively blend into your wall. Up to 120 W power load handling.
