The DS04-254-1-03BK-SMT is a 3-pole surface-mount DIP switch from Same Sky (formerly CUI Devices) designed for circuit configuration and control applications. It features a 2.54 mm pitch with a raised black actuator and operates at rated voltages up to 24 Vdc (switching) or 50 Vdc (non-switching) with maximum switching current of 25 mA per pole. The switch exhibits excellent electrical characteristics including contact resistance of 50 mO initial and 100 mO after life testing, insulation resistance of 100 MO at 500 Vdc, and withstanding voltage of 500 Vac. With an operating temperature range of -40°C to +85°C, switch travel of 0.9 mm, and rated life of 2000 cycles, this component is ideal for embedded systems, industrial control panels, and consumer electronics requiring reliable manual configuration options.
