Schlegel’s modular M series contact blocks are color coded for easy visual reference. The contact block modules fit together and then they snap into the module holder for quick assembly. Schlegel’s M contacts can be combined for up to five module units per operator (button). Modular contacts allow more “standard” customization for the customer’s requirements. Each block has finger proof terminals for safety.

The contact blocks shown below are only a small sampling of what is available. Please open the attached (pdf) catalog for a complete list of products, the technical specifications as well as the bulbs available for the lighted units in this series.
