The 7.0×3.5mm THT tactile switch – Reliable Top-Actuated combines a compact outline with the security of through-hole solder joints. Ø0.7 mm leads and a proven land pattern (Ø1.0 mm holes, 5.95 mm span) make assembly dependable, while silver-plated H62Y contacts keep resistance low. Rated 12 V / 0.05 A with 250 gf actuation and 30k cycle life, it provides a crisp feel for everyday user interfaces. Delivered on tape-and-reel for automated insertion and built from UL-grade plastics and stainless steel, it’s a practical choice for remotes, consumer keypads, and portable devices.
