SD04H1SB is a 4-position SPST low profile DIP switch from the SD Series, featuring a sealed extended 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 RoHS compliant design and process sealing that withstands soldering and cleaning processes, this switch is ideal for address switching in industrial controls, logic switching for computers and peripherals, and function controlling applications.
