The use of limit switches with normally open and normally closed contacts when using the two limit switches, one with a normally closed contact and one normally-open contacts, achieves a high level of security. However, it should be understood that failure of one circuit breaker is difficult to establish the safety of the operator and will depend on proper operation of the second switch.
