Features

1.4.7mm×5.2mm

1.This is a new concept in surfacemounted switches. It is ultra compact and can be mounted on a base with external dimensions 4.7mm×5.2mm.

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.
