The 90B03ST is a 3-position thru-hole DIP switch designed for machine insertion with a molded sealed base and optional top tape seal. It features high-pressure, reliable contacts with a contact resistance of =20 mO initially and =100 mO after life testing, ensuring consistent electrical performance. The switch has a length of 0.370 inches (9.4 mm) and is designed for 0.100 × 0.300 inch on-center holes, with a mechanical life rating of 2,000 operations per switch position. Operating over a temperature range of -40°C to +85°C with an insulation resistance of 5,000 MO initially and 1,000 MO after life, the 90B03ST is ideal for applications requiring reliable configuration settings in industrial equipment, telecommunications, and consumer electronics where compact, durable switching is essential.
