*1. The lever can be set to any desired position by turning the operating position indicator.

*2. In terms of construction, the Switch is a General-purpose Limit Switch rather than a Safety Limit Switch.

Note: Variation occurs in the simultaneity of contact opening/closing operations of 2NC contacts. Check contact operation.

*1. The operating characteristics of these Switches were measured with the roller level set at 31.5 mm.

*2. The operating characteristics of these Switches were measured with the rod level set at 140 mm.

*3. Only for slow-action models.

*4. Only for snap-action models.

*5. Reference values.

*6. Must be provided to ensure safe operation.
