The MDG601S is a single-pole double-throw (SPDT) transfer DIP switch designed for reliable switching and signal routing in electronic circuits. It features gold-plated, self-cleaning contacts with a contact resistance of 50 mO maximum initially and 100 mO maximum after life testing, ensuring consistent electrical performance. The switch is constructed with UL94V-O polyamide materials and offers an electrical life of 2000 cycles minimum with a mechanical life of 3000 cycles minimum. Operating specifications include a contact rating of 25 mA at 24 VDC for switching applications, an operating temperature range of -25°C to 70°C, and dual in-line 0.100" × 0.300" terminal spacing for standard PCB integration. The MDG601S is commonly used in instrumentation, control systems, and consumer electronics where reliable switching with minimal contact resistance is required.
