Speaker Switch

thingiverse

This simple enclosure securely holds four 4-way loudspeaker connectors and a single toggle switch, serving as a versatile stereo switch that connects two audio amplifiers to one set of speakers or switches one amplifier between two sets of speakers. I've found this setup particularly useful for connecting a surround sound amplifier to a Bluetooth amplifier driven by an Echo Dot, which controls the rear surround speakers. The SCAD file allows for printing not only the base and lid but also an optional mounting plate that attaches directly to the switch. This convenient feature enables me to hang the enclosure discreetly behind furniture, leaving only the visible switch exposed. What's more, there is ample space inside the enclosure to install a pair of miniature DPDT relays in place of the toggle switch, effectively making it possible to control the setup remotely.
