Tactile Switch 5×5 mm SMT DW-TS-S05570X-XXTR-01 is a compact, top-actuated SPST-NO tact switch for keypads and HMI inputs. It uses gull-wing SMT leads on a 5.0×5.0 mm footprint and a round plunger (Ø1.7±0.2 mm). The recommended land pattern is 5.00×2.80 mm with 0.70 mm pad width and 2.30 mm spacing.
Applications: Remote controls, wearables, IoT nodes, handheld instruments, consumer keypads, automotive accessories.
Highlights: 5×5 mm low-profile SMT footprint; top-actuated round plunger; 160/250 gf force options; 0.15 mm travel; 70k-cycle life; −40~+85 °C; SPST-NO; tape-and-reel.
Tactile Switch 5×5 mm SMT DW-TS-S05570X-XXTR-01 is a compact, top-actuated momentary SPST-NO switch for keypad and HMI inputs where board space and feel consistency matter.
