The 3-5435640-6 is a DIP switch from the 7100 series designed for dual in-line package programming applications. It features a sealed rocker (top actuated) actuator with a single pole-single throw configuration and contains 5 individual switches. The switch is thru-hole mounted on PCBs with a centerline spacing of 2.54 mm (0.100 in) and termination post length of 3.56 mm (0.140 in). The contacts are made of copper alloy with gold (30 µm) over nickel (50 µm) plating, and the housing is blue polyester material. This switch is RoHS and ELV compliant, wave solder capable to 240°C, 260°C, and 265°C, making it suitable for industrial control, equipment configuration, and embedded system programming where reliable, sealed switching is required.
