Product Description
Product Overview
The Littelfuse MDRR-DT is a miniature changeover reed switch designed for versatile applications. Featuring a hermetically sealed design, it ensures reliable operation unaffected by its environment. This SPDT (Single-Pole, Double-Throw) switch is capable of switching up to 175Vdc at 5W, making it suitable for low-power applications including position sensing, reed relays, industrial controls, office equipment, home appliances, and security systems. Its zero operating power requirement for contact closure and excellent performance with microcontroller logic level loads highlight its efficiency and adaptability.
