Small-format switches ideal for consumer electronics and industrial applications

Littelfuse has introduced the MITI-7 Series Ultra-Miniature Reed Switch, a Form A (single-pole, single-throw normally open or SPST-NO) switch that’s hermetically sealed in a 7-mm-long glass envelope. The series provides sensitivity options ranging from 6AT to 20AT, far wider than current magnetic switches of similar size, which were limited to a range of just 6AT to 10AT. New automated assembly equipment has enabled the company to boost production capacity for these small-format switches, which aid circuit designers to save space on crowded circuit boards.

Typical applications for the reed switches include position and speed sensing in a broad array of markets including appliances, building and home automation, consumer electronics, data centres, industrial, and healthcare.

The MISM-7, a surface-mount version of the MITI-7, is also offered. Both can switch 170VDC at 10W and provide high insulation resistance (1012Ohms min) and low contact resistance (<150milliOhms).

“The MITI-7 Series is built on fully automated equipment with precision controls,” said Max Shi, product marketing manager, Sensors at Littelfuse. “The increased capacity and superior quality standards this equipment supports help us to supply these reed switches to the global marketplace at much more competitive prices.”
