KSK or SW GP501 Series Reed Switch
The GP501 Series is a compact, high-performance reed switch engineered for precision and durability in demanding applications. With its robust glass encapsulation and reliable single-pole, single-throw (SPST) normally open contact configuration, the GP501 delivers consistent switching performance across a wide range of environments.
Its small form factor makes it ideal for use in space-constrained designs, while its dependable magnetic sensitivity ensures accurate actuation. Whether used in automotive systems, industrial controls, or consumer electronics, the GP501 Series offers a versatile and efficient solution for non-contact switching needs.
