Manual Soldering: See Profile B in Supplement section. Cleaning: These devices are not process sealed. Hand clean locally using alcohol based solution. Standards & Certifications The HB2 pushbuttons have not been tested for UL recognition or CSA certification. These switches are designed for use in a low-voltage, low-current, logic-level circuit. When used as intended in a logic-level circuit, the results do not produce hazardous energy.
Series HB2Subminiature Audio/Video Pushbuttons www.nkk.com D19 IndicatorsAccessoriesSupplement Tactiles KeylocksRotaries Pushbuttons D Illuminated PBSlides Programmable TogglesRockersTouch Tilt Distinctive Characteristics Quiet actuation combined with crisp tactile feedback suited for broadcast equipment. Full face illumination with choice of red/green or red/yellow bicolor LEDs, as well as simultaneous bicolor illumination which produces amber. Option of legends on caps or film insert. Compact design with short body .669” (17.0mm) from PCB to top of cap and .295” (7.5mm) square cap. Sliding Twin Crossbar (STC) mechanism provides unequalled logic-level reliability, contact stability, smooth positive detent actuation, and long life. Crimped power terminals ensure secure PCB mounting and prevent dislodging during soldering. Suitable applications include broadcast, telecommunication, and medical equipment, as well as measuring instruments, etc. Actual Size
