NKK Switches' SM series features an ultra-miniature slide with ON-OFF legend marking on the actuator for improved operational efficiency. SM series ultra-miniature slides have compact dimensions allowing for high density, side-by-side, or end-to-end mounting within tight dimensional applications. The twin sliding contact mechanism with self-cleaning action provides smooth actuation and produces high contact reliability. Insert molded terminals lock out flux, solvents, and other contaminants.
