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.
