NKK Switches Process Sealed Subminiature Antistatic Toggle Nkk Switches B29AH

The B Series is a subminiature, antistatic toggle switch designed for logic-level applications, featuring a sealed body with epoxy-coated terminals to prevent contamination and support soldering and cleaning. It has a 2.54mm x 2.54mm terminal spacing, a 26° angle of throw, and operates within a -30°C to +85°C temperature range. The switch utilizes an STC contact mechanism for positive detent actuation and logic-level reliability. Contact ratings are 0.4VA maximum at 28V AC/DC, with 50mΩ maximum contact resistance and 500MΩ minimum insulation resistance. Mechanical life is 100,000 operations for On-None-On and On-Off-On circuits, and 50,000 for others. The package is PCB-mount with straight terminals, and the locking lever and threaded bushing options support panel mounting per IP65. It meets UL94V-0 flammability standards. The part number B29AH corresponds to a double-pole, ON-OFF-(ON) circuit with a short paddle and straight PCB terminals, within the series specifications.
