About the actuating object
The roughness and hardness of the object’s surface significantly affects the operat-
ing life of the switch. The following specifications are recommended.
Roughness Hardness
Approx. Ra 6.3 Approx. HV 450
Note
•
If grease is applied to the sliding parts of the roller, actuating object, etc., they
will move more smoothly.
●
Overtravel and force
To ensure reliable operation, set overtravel (O.T.) between 1/3 to 2/3 of the over-
travel stated in the specifications.
Handling Precautions
•
Do not apply excessive force (three times the O.F. or more) to the lever beyond
the operating limit position. Doing so may cause faulty operation.
