Product details

3.5 mm stereo jack with two internal switches

The STX-3150-5C-1 is the 5-contact member of Kycon's STX-3150 phone jack series, accepting a 3.50 mm (1/8") mini plug for stereo TRS signals.

5 contacts vs 3 contacts — switch count differs

The STX-3150-5C-1 carries 5 contacts with two internal switches, while the same-series STX-3150-3C-1 carries 3 contacts and no internal switch — the M6x0.5 thread, 3.50 mm mating diameter, and through-hole right-angle mounting are shared across both variants.
