Rubber seal construction prevents contact contamination and allows automated soldering and cleaning. Minimal operating force and short stroke permit light touch operation. Dome contact gives crisp tactile and audible feedback to positively indicate circuit transfer and assures high reliability and long life. Wide choice of body shapes and colors. Actual Size Crimped terminals provide a spring type action to ensure secure mounting and prevent dislodging during wave soldering. Space saving body dimensions provide for compact, side-by-side mounting on a standard grid. Terminal spacing conforms to standard .100 (2.54mm) PCB grid.
