SMALL METAL PARTS TO RESOLVE ALL TYPES OF ELECTRICAL FAULTS

electrical contacts

Our company Arzuffi srl, is the leading manufacturer of small metal parts, including bushings, clamps and customised moulded small parts among others.

The production of electrical contactsis particularly important for our company. They are pieces of metal with superior conductivity that are typically composed of gold or silver, but which can also be manufactured with other cheaper metals, such as brass.

These electrical connectorscan also be coated with metals for superior conductivity on the contact surfaces. To make the contacts adhere to the connectors we usually use crimping. It is a process that allows you to physically and electrically connect a power cable to a suitable terminal or connector.

ELECTRONICS TERMINOLOGY: WHAT ARE DIRECT AND INDIRECT ELECTRICAL CONTACTS?

Be careful!

In Electronics we talk about "direct electrical contact" when a person touches an active part of the system, otherwise known as "the live part". These live parts are usually the electrical conductors, the clamps or the connection for a lamp. In the event of direct contact with the human body it causes the closure of an electrical circuit, comprising of: the part of the line concerned, grounding, ground and subject. So be very careful when you handle particular components, such as electrical connectors.

 

Indirect contact in the event of electrical failures

"Indirect contact" is the case in which a subject touches metal parts which have an accidental and unpredictable live voltage. This typically occurs in the case of electrical failures, which can often be invisible. Therefore, it is worthwhile to always exercise caution: the metal casing of the electric appliance or the "ground wire" could be live. If this happens, the subject will be hit by a passage of electric current moving towards the ground, which can also be very violent.
