Littelfuse Inc. extends its K5V Sequence of illuminated tactile switches with the discharge of recent K5V4 fashions together with the gull-wing and a pair of.1-mm pin-in-paste (PIP) variations suitable with reflow soldering. These switches goal a variety of functions, resembling knowledge facilities, community infrastructure, industrial gear, and professional audio/video programs.
The K5V4 is the primary long-travel, single pole/double throw (SPDT) illuminated tactile swap in a reflow-capable SMT bundle, Littelfuse stated, filling a essential hole available in the market. They permit direct SMT meeting for the primary time, cut back manufacturing prices, help increased throughput, and enhance end-product high quality, whereas sustaining sturdiness and tactile efficiency, the corporate added.
The K5V4 switches are reflow soldering-compatible due to the usage of a high-temperature polyarylate (PAR) materials with a 250°C thermal deformation threshold, eliminating the necessity for silicone sleeves or particular dealing with. They’re suited to producers transitioning from wave to reflow soldering processes.
Different options embody SPDT contact configuration with normally-open and normally-closed choices, a pointy tactile response with audible click on and 4N working drive, and built-in high-brightness LEDs in a wide range of colours and bi-color choices.
For better reliability, these switches present a compact, dust-resistant design for dependable operation in dense boards, and gold-plated dome contacts for long-term contact efficiency. They’re out there in SMT (gull wing) and THT (PIP) variations for design flexibility.
The K5V tactile switches are at the moment out there in tape and reel format, with portions starting from 1,000 to 2,000 items. Samples might be requested via approved Littelfuse distributors.
