Abstract
In order to form a locking mechanism for a switch-on button of a circuit breaker which has a simple and inexpensive configuration, the locking mechanism has a locking element which is mounted rotatably on the switch-on button. The locking element, held directly in a first position by a first spring, enables actuation of the switch-on button and, directly in the switched-on state of the circuit breaker by a second spring, can be moved into a second position. The switch-on button of the circuit breaker is locked to prevent actuation in the second position.
Claims3
A locking mechanism for a switch-on button of a circuit breaker, the locking mechanism comprising:
- a first spring;
- a second spring;
- a locking element rotatably mounted on the switch-on button, said locking element, held directly in a first position by said first spring, allowing the switch-on button to be actuated and, in an ON state of the circuit breaker, can be placed directly in a second position by said second spring, wherein, in the second position, the switch-on button of the circuit breaker is locked against actuation;
- and
- said second spring engaging with said locking element and a switch shaft lever of the circuit breaker.
