| Low Profile Process Sealed Tactiles Series JB Distinctive Characteristics Choice of dimensions from PCB to top of cap adds to design flexibility. 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 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.
