Dimensions
Note: Unless otherwise specified, all units are in millimeters and a tolerance of ± 0.4 mm applies to all dimensions.
■ Terminals
Screw Terminals (-B)
Note: Appropriate terminal screw tightening torque: 0.78 to 1.18 N·m.
■ Mounting Holes
All switches can be mounted using M4 mounting screws with plane
washers or spring washers to securely mount the Switch. Tighten the
screws to a torque of 1.18 to 1.47 N·m.
Note: Mount using either the side mounting holes or the panel mount plunger, not both. If using the side mounting holes, then remove the hexagonal nut(s)
