Its function is to prevent repeated plugging and unplugging of cables and wear and tear on the contact points of the socket. This is a great idea to solve the problem of plugging and unplugging speaker cables.


Features: High current silver alloy contact switch, 2.5 square metres of silver plated single crystal copper wire, pure copper gold plated banana jacks, selected parts are hand welded using a soldering station.

Notice:
There is no protection or impedance matching circuitry inside the switcher, but with the exception of many tube amps, it is very unhealthy to switch on with no load (no speakers) connected; so if you have a tube amp, you can either use a switcher with tube protection, or switch off the amp and then switch it on again after switching.
