Circuit breaker having a bimetallic snap-action disk

A circuit breaker, comprising:

• a housing;
• a fixed contact connection being disposed in said housing and having a fixed contact;
• a bimetallic connection disposed in said housing adjacent said fixed contact connection;
• said fixed contact connection and said bimetallic connection being identically shaped flat contacts having a longitudinal axis and a central region bent out in a trough defining an outside of said trough and an inside of said trough;
• a bimetallic snap-action disk fixed to said bimetallic connection and having a contact end with a bimetallic contact in a contact-making, overlapping position with said fixed contact of said fixed contact connection;
• said flat contacts being inserted into said housing mutually rotated about said longitudinal axes, with said bimetallic snap-action disk fixed to said outside of said trough of said bimetallic connection and said fixed contact fixed to said inside of said trough of said fixed contact connection;
• a spring-loaded isolating slide moving between said fixed contact and said bimetallic contact upon said fixed contact and said bimetallic contact opening, said isolating slide having an illuminated pushbutton formed of a transparent material and having a material cutout formed therein;
• and
• an electrical luminous element for illuminating said pushbutton, said luminous element being fixed in position inside said housing in vicinity of said material cutout.
