Since the founder of Elektro began to develop contact lubricants in the 1950s, it has maintained a leading edge in this field
Elektro has already provided services to the automotive, military, aerospace and We have gained an unparalleled reputation for producing and supplying lubricants to the industrial and domestic switch manufacturing industries. The series of lubricants that have been developed to serve a variety of rapidly developing industries have good electrical properties, lubrication and plastic compatibility, and improve movement and touch.
Contact lubricants are specially formulated greases or oils that reduce friction while improving the electrical performance of the metal current-carrying surfaces of switches and connectors. In thick films, Elektro contact lubricants are insulating and prevent electrical leakage. Ultra-thin films, such as the oil film formed between closed metal contacts, are conductive due to the quantum tunneling effect. The value of the oil film is neutral to avoid surface corrosion.
Even a perfectly designed switch can be more efficient through the use of contact lubricants, and if contact lubricants are considered during the product design phase, expensive raw materials (including plastics and contacts) can be avoided. metal), thus saving a lot of production costs.
Experiments have shown that contact lubricant can extend the service life of the switch by more than %, while showing excellent performance in various environments, eliminating expensive maintenance costs.
How electric shock lubricants work
With the emergence of new alloys and plastics and customer requirements, contact technology is also constantly developing. However, it is still impossible to completely solve the main problems causing switch failure, such as the inability to produce completely smooth metal contact surfaces,
This leads to the following problems:
Heating:
Because the current is only determined by the design A small portion of the surface area is used to carry the load, so the heat generated is concentrated on the protruding parts, resulting in the formation of a high-resistance oxide layer. Such hot spots reduce the efficiency of the switch and can cause complete switch failure when the two surfaces are welded together.
Arcing:
Arcing (tiny electrical sparks) often occurs when unlubricated contacts open and close. The ionization of the air and the associated temperature increase can cause metal to migrate across the contact surface, forming new bumps and grooves.
Mechanical wear
Mechanical wear is caused by two contact surfaces rubbing against each other and may appear on all metal interfaces, whether stationary or moving. Mechanical wear on stationary contacts (connectors) is often not noticeable. But the fact is: vibration and temperature changes can cause small movements of connectors and closed contacts, which is often referred to as friction and corrosion. As the contact surface wears, friction causes metal particles to rush out from the protrusions onto the plating surface, causing oxidation or wear of the surface and underlying metal. In addition, free metal particles can cause discontinuous signal transmission and eventually cause switch failure.
Silicon Contamination:
Products containing silicon cannot be used in switchgear because silicon may migrate over large areas. If silicon is present on moving or vibrating contacts, it will react to form silicon carbide when an arc is generated. These grains can wear away contact surfaces and may cause electrical breakdown.
The use of lubricants significantly increases the effective contact area of the contact and fills any air gaps, thereby eliminating hot spots, reducing contact resistance and preventing arc friction wear. Elektro offers contact lubricants that eliminate contamination problems.
Finally, and most importantly, discuss the use of lubricants with Ellico during the design stage to ensure that the right product is used in the right field. Factors to consider include: voltage and current operating temperature range contact metal cycle times and related plastic materials.
The tactile feel of a switch operating has become a performance indicator, especially in the automotive industry. The technical advantages of contact lubricants allow them to determine the tactile feel of a certain switch, which may appear forceful and decisive on the dashboard of a commercial vehicle, but smooth and quiet on a luxury sedan.
