Where there are electric switches, there are always electrical contacts.

Electricity is necessary for our daily life.

There are many different types of electromagnetic switches, each for carrying and cutting off various electrical capacities.

As well as manufacturing contact configurations tailored to our customers' individual needs, we have pioneered the development of contact materials for use with all types of electricity.

Selecting materials to meet our customer's criteria, we then develop and produce our products – creating products together with our customers is our company mission.

We have been in business as a specialist maker of electrical contacts for over 70 years and, pursuing our mission. We have built up a customer base from a wide range of industry sectors both in Japan and overseas.

As we face environmental issues, energy-saving and increasing prices for scarce materials, supporting our customer's business by creating ever more innovative products remain our priority.

• Solid contacts (rivet or wire) are generally used however, do contacts always need to be solid types?
• To maintain the strength of bonded parts of contacts, have there been limitations due to the thickness of chips?
• Is it possible to increase the use of composite materials instead of pure silver to reduce cost?
• Is it possible to increase the use of composite materials instead of pure silver to reduce cost?

• Is it possible to improve contact resistance without using Au and Ag plates?

• Is it possible for us to undertake processes which customers would otherwise outsource to a third party company or do themselves?

Silver is an essential material for making contacts and is a precious natural resource. With prices ever increasing, at Chugai Electric Industrial Co., Ltd, we refine used silver in-house.

We collect scrap contacts from our customers. After refining, we calculate a refined silver price (based on our calculation standard) and pay this back to our customers.

We refine silver of 99.99% purity in-house and, after analyzing, we recycle the material for use in new contacts.

Chugai group quality policy statement responds to International Standards of ISO 9001:2015, ISO 14001:2015, ISO/IATF 16949:2016 and at the same time, we maintain the related laws & regulations and satisfy the expectation of all the stakeholders’ in-line with our mission.

Leveraging on the (Certifications) and supported by state-of-the-art manufacturing facilities, we believe in manufacturing and quality philosophy of process orientation and improvements through Best Manufacturing Procedures, 5S, SPC and 7 QC TOOLS.

Chugai group are committed to delivering based on an effective quality system, the best products and customer satisfaction that exceed our customers’ requirements and expectations.
