Compact bidirectional 3.5 mm audio switch

This passive switcher lets you route stereo signals between two sources and one output or one source and two outputs with a single button press. It is built for desktop users, gamers and mobile listeners who want to swap headphones, speakers or soundbars without unplugging cables. The aluminium shell measures 2.6 by 2.5 by 1.1 inches and draws no external power.

Passive operation with silent switching

Because the unit requires no power supply it adds no noise, heat or standby draw to the signal chain. The mechanical selector toggles instantly and silently, preserving audio fidelity across all connected 3.5 mm devices. A 3.3‑foot auxiliary cable is included for immediate setup.

Two‑way routing for one‑to‑two or two‑to‑one setups

The bidirectional architecture supports either 1‑in‑2‑out or 2‑in‑1‑out configurations, so you can send one source to two listening devices or switch between two sources into a single speaker or headphone. It does not split a signal to both outputs simultaneously.

Questions about this item

How do I connect the 1-metre 3.5mm cable and which jacks are inputs versus outputs?

Plug the supplied 3.3-foot cable into the single 3.5mm jack on one side for the source, then connect your headphones or speakers to the two jacks on the opposite side; press the button to toggle between 2-in-1 and 1-in-2 modes.

Will the mechanical selector or gold-plated contacts need cleaning or replacement over time?

The passive switch uses a tactile button and female-to-female 3.5mm ports with no active electronics, so only occasional contact cleaner on the jacks is needed if crackling appears after extended use.

At what point does the aluminium chassis become too hot during continuous switching?

The unit draws no external power and handles only line-level analogue signals, so the aluminium shell stays at ambient temperature even with constant 2-in-1 or 1-in-2 operation.
