Bright, full-face illumination with red, green, or yellow LEDs for attractive, functional panel layouts. Higher operating force type provides more pronounced operating feel. Dome contact gives crisp tactile feedback to positively indicate circuit transfer and assures high reliability and long life of up to 5,000,000 operations. Rubber seal construction prevents contact contamination and allows automated soldering and cleaning. Slanted terminals provide a spring type action which ensures Actual Size secure mounting and prevents dislodging during wave soldering. Molded-in terminals are part of the sealed construction which allows automated soldering and cleaning. Terminal spacing conforms to standard .100 (2.54mm) PCB grid.
