The 76SB03T is a 3-position thru-hole DIP switch manufactured by Grayhill, featuring a raised rocker actuator style with a sealed base and spring and ball contact mechanism. The switch has a length of 0.380 inches (9.65 mm) and operates with a contact resistance of =30 mO initially and =100 mO after life testing. It is rated for 2,000 mechanical operations per switch position and supports make-and-break current ratings of 1 mA at 5 Vdc, 50 mA at 30 Vdc, or 150 mA at 30 Vdc. The switch operates reliably over a temperature range of -40°C to +85°C and features a maximum current carry rating of 5 A with a 20°C temperature rise. This DIP switch is ideal for industrial control panels, consumer electronics, and instrumentation applications where compact, reliable switching with sealed protection is required.
