SD02H0B is a 2-position low-profile DIP switch featuring a sealed flush actuator with top tape and thru-hole terminals, designed for space-constrained applications. The switch is process-sealed to withstand soldering and cleaning processes, with a low-profile design that saves board space. It offers SPST (Single Pole Single Throw) functionality with a contact rating of 100 mA at 50 V DC maximum carry current and 0.1 mA at 5 V DC minimum to 100 mA at 25 V DC switching current. The switch maintains contact resistance below 50 milliohms typical at 2-4 V DC with 100 mA load, and provides 2,000 make-and-break cycles at full load with an operating force of 100-700g initial. Common applications include address switching for industrial controls, logic switching for computers and peripherals, and function control in various electronic systems.
