MO-1422 Miniature Off-center Reed Switch
Description
This off centre contact Form A reed switch is designed for highly sensitive magnet applications. Measurements are always taken with the contact overlap portion centered to the length of the test coil, with the width of all blades in a batch of switches, facing one way, for better in-group measurement accuracy. The cropped version is suitable for smaller plastic housings and can be soldered to cables, the SMD version is suitable for reflow on PCBs, and the vertical and horizontal mount versions are suitable for mounting on through hole PCBs.
