Principle

A bimetallic strip consists of flat strips of two metals with different thermal expansion coefficients fixed together on each other. When the strip is heated, it bends into the direction of the metal which has the lower thermal expansion coefficient.

The bimetallic strip is therefore suitable for opening electric circuits, e.g. in cut-outs, or as an overheating safety switch in electric irons or power supply equipment, or for closing them, e.g. in alarm systems, when the temperature of the surrounding air exceeds a maximum permissable value.

Benefits

  • No additional cable connections between the building blocks needed - clear arragned and quick setup
  • Contact saftey due to puzzle blocks system
  • Corrosion-free gold plated contacts
  • Doubled earning sucess: Electric circuit diagram on top, real components can be seen unterside
