Note: 1. Unless otherwise specified, a tolerance of 0.4 mm applies to all dimensions.
2. Use the dog within 35 mm of the tip of the actuator and keep the total travel to 70 mm or less.
Slow-action (1NC/1NO) (2NC/1NO) (2NC) (3NC)
Note: Variation occurs in the simultaneity of contact opening/closing operations
of 2NC, 2NC/1NO, and 3NC contacts. Check contact operation.
