BD03 is a 3-position SPST standard profile DIP switch designed for address switching and logic control applications. It features an extended actuator for easy actuation, open bottom construction for solder washing, and is RoHS compliant. The switch offers a contact rating of 100 mA max at 50 V DC (carry) and 100 mA max at 5 V DC (switch), with contact resistance below 50 milliohms typical. Operating temperature ranges from -40°C to 85°C, and the switch provides 10,000 make-and-break cycles of mechanical and electrical life. Common applications include address switches for industrial controls, logic switching for computers and peripherals, and function controlling for various equipment.
