Dimensions
Note: 1.
Unless otherwise specified, all units are in millimeters and a tolerance of
±
0.4 mm applies to all dimensions.
2.
Terminal numbers are not indicated on this switch. With the switch turned over so that the logo mark “OMRON” is visible on the upper
part of the rear side of the switch base, the terminal on the right of the logo mark is numbered “1” and that on the bottom right is “3.”
Accordingly, two terminals on the left side are numbered “2” and “4” respectively.
