Tactile switch 3.5×4.6 SMD – Ultra-Slim Top-Actuated, 1.7 mm

Tactile switch 3.5×4.6 SMD – Ultra-Slim Top-Actuated, 1.7 mm –  delivers a sharp, repeatable click without consuming vertical space. The 1.7 mm profile clears tight bezels, while a rectangular four-pad land pattern (≈4.50 mm span, ≈2.20 mm row spacing) speeds routing and yields robust joints in reflow. A silver-plated stainless dome and LCP housing preserve low contact resistance through tens of thousands of actuations. With a firm 250 gf feel, 0.13 mm stroke, and 12 V/50 mA rating, it drops cleanly into wearables, sensors, and portable instruments where reliable, tactile confirmation improves the user experience.
