Key Switches Enhance Tactile Feedback
Using silver- or gold-plated dome inserts, C&K Components’ K5G and K5A2 snap-acting key switches are said to allow for enhanced user feel for tactile feedback. The 8.20-mm × 8-mm × 6-mm K5G exhibits mean operating force of 3.7 N for the first stroke and 6.5 N for the second stroke, and travel of 0.50 mm and 0.85 mm for the first and second strokes, respectively. The double-action SPST device demonstrates an operational life of 30,000 actuations in car window and sun-roof controls and multi-function controllers. The 8.20-mm × 8-mm × 4.50-mm K5A2 presents mean operating force of 5.5 N with a 6-N version available; electrical travel of 0.5 ± 0.1 mm, and operational life of 50,000 actuations. The momentary-action, normally-open unit works in automotive, computing and networking equipment. From $0.97 to $1.50 in 1,200 quantities min.
