The maximum operating rate is 3600 cycles/hour with a load factor of 0.5. The minimum actuation speed for snap-action contacts is 0.01 m/minute and for slow-break contacts is 6 m/minute.

Mechanical Characteristics:
The switches have a mechanical durability of 10 million operating cycles. The minimum force or torque for tripping is 8.5 N, and for positive opening, it is 42.5 N.

References and Models:
The document provides references for various models of limit switches, including those with different types of heads and operators, such as metal end plungers and steel roller plungers. It also includes details on modular units for mobile equipment with different connector types.

Graphical Data:
The document includes graphical data showing the relationship between current in amperes and the number of operating cycles for different switch configurations and connectors.
