Nidec Copal MFS Slide Switch

The MFS series slide switches from Nidec Copal (formerly Fujisoku) are renowned for their adaptability and high-quality construction. This series provides an expansive variety of circuit options ranging from standard SPDT to high-density 4PDT configurations. By offering such a broad selection, the Nidec Copal MFS Slide Switch allows for intricate multi-circuit control within a single, space-efficient component.

Operationally, these switches utilize a non-shorting (break-before-make) timing mechanism, which is critical for protecting sensitive circuits by ensuring one connection is fully disengaged before the next is established. Whether you are integrating these into a modern automated system or a classic instrument panel, the various termination styles—such as PC Right Angle and Solder Lug—ensure compatibility with diverse assembly processes and housing constraints.

Description

The Nidec Copal MFS Slide Switch is a highly versatile and compact switching solution engineered for reliable performance across a wide range of electronic applications. With 20 distinct types available, this series offers engineers the flexibility to choose the exact configuration needed for complex PCB designs and interface requirements.

The Nidec (formerly Copal/Fujisoku) MFS Series is a line of sub-miniature slide switches designed for low-current applications. These are popular in consumer electronics, telecommunications, and industrial equipment due to their high reliability and diverse mounting options.
