UM-0018 Ultra-miniature Reed Switch

5.0 mm and 7.0 mm Glass, Form A, Center Contact

All dimensions in mm

These highly sensitive, form A reed switches are designed for low power, high speed switching applications,

where there is a size restriction. The 5 mm glass version is built for use in very compact applications, and

the 7 mm glass version is built for lower contact resistance, and can switch higher loads.
