Features
1.3.2mm×4.9mm
1.This is a new concept in surfacemounted switches. It is ultra compact and can be mounted on a base with external dimensions 3.2mm×4.9mm.
2.The compact form of these switches enables high layout flexibility and easy set design.
3.High-speed mounting using a chip mounting machine is possible due to the lightness and structural advantages of the switch.
4.Reflow soldering is possible using a reflow furnace.
