Resistance Contact Welding

Economical production of electromechanical switching elements

By the CONTACTOMAT system we basically mean the four different processes listed below for the manufacture of electromechanical switching elements.

The CONTACTOMAT system offers the following advantages:

• Great savings in precious metals

• Metallic bonding between contact carrier and contact material, i.e. excellent mechanical and electrical properties

• Miniaturization of the switching elements

• High production with consistently high quality and reduced costs thanks to automation

• Economical solution thanks to scrap-free processing of the expensive precious metal contacts

The CONTACTOMAT system is based on a modular principle using proven modules and elements and is characterized by the following features:

• Robust, simply constructed and flexible automatic machines

• Easy to operate and service, good accessibility and short changeover times

• State-of-the-art control and automation technology ensures optimum process and operational reliability

• Fully automatic processing of endless contact materials (wire or profile) or prefabricated contact plates (bulk material).

• Fully automatic processing of endless contact carrier strips or prefabricated contact carriers (bulk material).

CONTACTOMAT - CH

Examples of finished contact elements with different sizes, shapes, materials and number of contacts depending on requirements.

CONTACTOMAT - CV

Examples of contact elements in endless strip form with up to 750 welded contacts per minute on one production line.

Examples of finished contact elements with different sizes, shapes, materials and number of contacts depending on requirements.

CONTACTOMAT - CA

Examples of contact elements using "direct" resistance brazing with different sizes, shapes, materials and number of contacts depending on requirements.

Examples of contact elements by means of "indirect" resistance brazing or induction brazing as well as resistance brazing in strip form.

CONTACTOMAT - CN

Examples of seam welded contact tapes with different sizes, shapes, materials and number of contact lines according to requirements.

Examples of seam welded bi- or tri-metal contact tapes (see left and right side of picture) with different sizes, shapes and materials depending on requirements.
