Surface Mount Detection Switch
D3SK
The smallest detection switch in the
industry (OMRON's data as of April 2008.)
Ultra small size and ultra low profile contributing to down-
sizing of sets devices. (3.0 x 3.5 x 0.9 mm (W x D x H)
A unique mechanism enables high contact reliability and
high precision operation.
Long stroke for easy installation is available.
Meet a variety of applications by contact and lever
variations.
