### Answer:

If an operating body stops near the operating position (OP) or the releasing position (RP) of a basic switch, it may create chattering or bouncing and cause problems. Set the switch within the allowable operation speed (catalog value) so as not to stop at the OP point and RP point.

### Explanation:

The operating stroke is the movement of the actuator caused by the operating body that is required for the switch to operate correctly. Operate the unit smoothly as described below, and do not stop its movement near the operating position (OP) or releasing position (RP). Set the switch pushing distance from 60% to 90% of the specified overtravel (OT) value. Beyond 90%, the actuator or switch may be damaged.

1. The actuator must normally be in the free position (FP). (The operating body is separated from the actuator.)
2. The motion of the operating body must not stop at the operating position (OP) and the releasing position (RP).
3. When the operation reverse position (suitable pushing of the actuator) is set, the motion of the operating body must be adjustable based on the specified overtravel (OT) value.
4. When the switch is placed in a device, the suitable pushing point of the operating body has to be 60% to 90% in the operating position (OP) to the total travel position (TTP).
