Y651050100P is a low-profile rotary DIP switch from the RTE Series designed for compact electronic control and configuration applications. The switch offers multiple position configurations including 2-position SPDT, 3-position SP3T, 4-position SP4T, 10-position BCD, and 16-position hexadecimal coding options, with both thru-hole and surface mount termination variants available. Key technical characteristics include a contact rating of 100 mA maximum at 30 V DC (gold contacts) or 50 V DC (silver contacts), mechanical life of 1,500 to 20,000 actuations depending on model, and contact resistance of 100 mO maximum initially with 150 mO after life. The switch operates reliably over a temperature range of -25°C to +85°C and features a robust stainless steel cover with miniature size construction. Common applications include timers, automation components, computer peripherals, alarms, access control systems, and instrumentation, where reliable position selection and coding are essential.
