Higher operating force type provides more pronounced operating feel. Rubber seal construction prevents contact contamination and allows automated soldering and cleaning. Choice of dimensions from PCB to top of cap allows design flexibility. 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. Slanted terminals provide a spring type action which ensures secure mounting and prevents dislodging during wave soldering. Actual Size Molded-in terminals are part of the sealed construction which allows automated soldering and washing. Terminal spacing conforms to standard .100 (2.54mm) PCB grid.
