Subminiature Pushbuttons Series HB Distinctive Characteristics Compact front panel design with 9mm square or round bezel. Rear panel threaded mounting. Behind panel depth of less than one inch. 8mm body diameter fits common size panel cutout. Latchdown feature gives indication of circuit status. Audible and tactile feedback with smooth and responsive operation. Dual, sliding contacts with self-cleaning action provide contact stability, high reliability, and increased operating life. Solder lug terminals have spacing of .100” (2.54mm) for choice of mounting. Longer normally closed terminal facilitates wiring and soldering. Molded-in terminals lock out flux, dust, and other contaminants. Illuminated models available and shown in the Illuminated Pushbutton section. Matching indicators available and shown at the end of Section M.
