Claims

[Scope of utility model registration request]

It has at least one pair of electric contacts surrounded by a housing and consisting of a contact point and a conductor, a protrusion is provided at the tip of the conductor of at least one of the electric contacts, and the protrusion is used to close the circuit of the electric contact. 1. A circuit breaker characterized in that the circuit breaker is formed so as not to contact the conductor of another electrical contact, and to be closer to the contact of the other conductor than the distance between the opposing contacts when opened.
