What this switch does

The SPRODIO T21 is a passive 3.5mm audio selector that lets you route two sources to one output or one source to two outputs. It suits anyone who wants manual A/B switching between a computer, TV or portable player without unplugging cables.

Limits of the 3.5mm analogue path

The box uses a 6A/125V toggle switch for lossless signal routing, but it cannot mix or sum signals — only one path is active at a time. It also needs no external power, so it cannot amplify or buffer long cable runs.

Installing and common issues

Plug the 3.5mm jacks in, flip the toggle to choose the active route, and it works immediately. The metal chassis measures 1.73 by 1.97 by .9 inches and weighs 50g, so it sits securely on a desk. The only common mistake is expecting both outputs to play simultaneously in 1-in-2-out mode.

Questions about this item

Should I pick the 2-in-1-out or the 1-in-2-out mode for my setup?

Choose 2-in-1-out to select between two sources like a computer and TV feeding one speaker. Choose 1-in-2-out to send one source such as an MP3 player to either headphones or speakers, not both at once.

What does the 6A toggle switch rating mean for everyday listening?

The 6A/125V toggle handles the tiny currents of line-level audio with a large safety margin, so it switches cleanly without adding noise or wearing out quickly.

How does the 3.5 mm jack interface limit what I can connect?

The three 3.5 mm sockets accept standard stereo mini-plugs from phones, PCs, TVs, headphones or powered speakers; they do not carry microphone, digital or balanced signals.
