The 500SDP1S1M2REA is a DPDT (double-pole double-throw) miniature toggle switch designed for PC board mounting applications. It features three switch positions with ON-NONE-ON functionality, allowing connections between terminals 2-1 and 5-4 in position 1, and 2-3 and 5-6 in position 3. The switch is rated for 0.4VA at 20V (AC or DC) with gold-plated contacts providing a typical contact resistance of 10 milliohms and an insulation resistance of 1,000 megaohms minimum. With a travel distance of 2.16mm and an electric life of 30,000 actuations at full load, this switch operates reliably across a temperature range of -30°C to 85°C. The device is RoHS compliant and ideal for applications requiring compact, reliable switching in consumer electronics, industrial controls, and instrumentation systems.
