The Neutrik NP2C-AU-SILENT is a 2 pole 1/4" professional phone plug, gold plated contacts, red coating, silent switch.
Special version of 2 pole plug with integrated switch which automatically mutes (shorts) a guitar cable to avoid annoying pops and squeals when hot swapping guitars. The integrated silent switch is based on the REED technology and guarantees a lifetime beyond 10'000 mating cycles.
Please note that the signal isn't muted with active electric bass guitars which have a tip-ring-sleeve tap to activate the power supply.

No corrosion or pollution of switch, durable and long-lasting
