The Neutrik NP2RX-AU-SILENT is a 2 pole right angle 1/4 inch professional phone plug with gold plated contacts, a red coating, and specially designed silent switch. This special version of the 2 pole plug has an 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 REED technology and guarantees a lifetime beyond 10,000 mating cycles. To further guarantee the electrical contact necessary for the Reed switch solder has been added between the Reed and Sleeve.
