SD08H0B is an 8-position low-profile DIP switch featuring a sealed flush actuator in the "OFF" position with top tape seal and thru-hole terminals. The switch employs SPST (Single Pole Single Throw) switching function with BeCu contacts plated with 10 µm gold and bright tin-plated brass terminals, all insert molded for durability. It is rated for 100 mA carry current at 50 V DC maximum and supports 2,000 make-and-break cycles at full load with contact resistance below 50 milliohms typical. The device operates reliably across -40°C to +85°C, features a low-profile design that saves board space, and is housed in a flame-retardant PPA case with nylon actuator (UL 94V-0). Common applications include address switching for industrial controls, logic switching for computers and peripherals, and function control in various electronic systems.
