SD04H0SB is a low profile 4-position SPST DIP switch from the SD Series, featuring a sealed flush actuator with top tape and surface mount (gull wing) terminals. It offers a contact rating of 100 mA @ 50 V DC max carry and 100 mA @ 25 V DC max switch, with contact resistance below 50 milliohms typical. The switch provides 2,000 make-and-break cycles of mechanical and electrical life at full load, with an operating temperature range of -40°C to 85°C. With its low profile design, process sealing capability, and RoHS compliance, this switch is ideal for address switching in industrial controls, logic switching for computers and peripherals, and function controlling applications.
