NKK Switches | GB25AV-XC

The GB Series Ultra Mini DPDT On-Momentary Vertical Through Hole Push Button Switch. Ultra-miniature size allows high density mounting, and extremely light weight of 0.25 gram makes these switches ideal for handheld equipment. Totally sealed body construction prevents contact contamination and allows time- and money-saving automated soldering and cleaning.

Award-winning STC contact mechanism with benefits unavailable in conventional mechanisms: smoother, positive detent actuation, increased contact stability and unparalleled logic-level reliability. (Additional STC details in Terms & Acronyms; see Supplement section.) .100” x .100” (2.54 mm x 2.54 mm) terminal spacing conforms to standard PC board gridspacing. Round terminals facilitate easier through-hole mounting on PC boards. Matching indicators available and shown at the end of Section M.
