The 78F01T is a thru-hole DIP switch featuring a 2-position, single pole/double throw (2PST) configuration with a raised slide mechanism for manual actuation. It measures 0.280 inches (7.1 mm) in length and incorporates spring and ball contact technology with a sealed base design for reliable operation. The switch is constructed with gold-plated brass shorting members, copper alloy base contacts, and matte-tin plated terminals, ensuring excellent electrical performance and durability. It delivers a mechanical life of 2,000 operations per switch position and maintains contact resistance of =30 mO initially and =100 mO after life testing. The 78F01T operates reliably across a temperature range of -40°C to +85°C and is ideal for applications requiring compact, reliable switching in electronic equipment such as configuration settings, mode selection, and circuit control in industrial and consumer devices.
