Switch Contact Point With AgNi Silver Alloy Contact Material
Switch Contact Point
silver switch contacts,
switch silver contacts,
switch electrical contacts
Used for AC or DC relays,
command switches, contactors,
optical controlled switches, temperature
controllers and machine timers, etc.
AgNi silver contact thickness:0.4mm
low and stable contact
resistance; good resistance against
welding and electric wear. Material
transfer is very little under DC condition.
Increasing nickel content can improve the
welding resistance but will also increase the
contact resistance and temperature rise.
AgNi silver alloy wire/copper wire
Contact material: AgNi silver alloy
Rivet Body and base material:
ETP copper T1 ,T2...
Characteristics and Applications for AgNi contact material
Contact Material in Huano:Type 1
AgNi10 and AgNi20 Properties
The nickel grains in the material are of fiber structure. The
material has high conductivity, low and stable contact resistance;
good resistance against welding and electric wear. Material
transfer is very little under DC condition. Increasing nickel
content can improve the welding resistance but will also increase
the contact resistance and temperature rise.
Main applications for AgNi10,AgNi20 contact material according to
AgNi contact material widely used to AC or DC relays, command
switches, contactors, optical controlled switches, temperature
controllers and machine timers, etc.
Contact Material in Huano:Type 2
AgNi10 T1,AgNi20 T1
AgNi10 T1 and AgNi20 T1 Properties :
The welding resistance and arc erosion resistance are obviously
improved by addition of a small quantity of additives.
Main applications for AgNi10 T1,AgNi20 T1 contact material
according to its properties:
Applied for high- and medium-current relays and medium- and
AgNi alloy Wire,AgNi alloy tips or AgNi alloy rivet
What are electrical contacts?
The contact is also called a tip, point, finger, wedge, button or
segment.A single or multi-pole electrical product that contains
movable and stationary contacts,
often including screws, springs and possibly other hardware is
called a kit or set.
A contact opens and closes
(makes and breaks) to engage or interrupt an electrical circuit.
They are usually used for switches,
relays, contactors and motor starters etc.
An electrical contact is defined as the interface between the
current-carrying members of electrical/
electronic devices that assure the continuity of electric circuit,
and the unit containing the
interface. The current-carrying members in contact, often made of
solids, are called contact
members or contact parts. The contact members connected to the
positive and negative circuit
clamps are called the anode and cathode, respectively.
Electrical contacts provide electrical connection and often perform
other functions. The
primary purpose of an electrical connection is to allow the
uninterrupted passage of electrical
current across the contact interface. It is clear that this can
only be achieved if a good metalto-
metal contact is established. The processes occurring in the
contact zone are complex and not
fully explained within the limits of present knowledge. Although
the nature of these processes may
differ, they are all governed by the same fundamental phenomena,
the most important being the
degradation of the contacting interface and the associated changes
in contact resistance, load,
temperature, and other parameters of a multipoint contact.

5 Quality control:
we provide Electrical switch contacts samples to customer for
checking before production; we will not produce until the sample is
approved; we will do the product inspection randomly in the process
of production to detect the problem in time, we also will select
random products to customers for checking according to customers
requirements after the completion of the production before
For the electrical silver contacts products with high assembly
requirements, we will ask customers to provide the assembly parts,
to ensure that the products can be assembled ok before shipment.
6. Provide valuable pictures anytime:
provide clear pictures of samples to customers for checking before
the shipment; provide pictures of products which is in the process
of producing; provide the detail packaging pictures showing the
quantity and packaging of each product clearly after the completion
7. Freight advantage:
many customers who cooperate with us for many years give feedback
that the freight charges that we offered is much lower than the
costs that the customers arrange the transportation by themselves,
in general, the price can be cheaper by 30 percent to 50 percent,
which help customers save shipping costs greatly.
Our sales department communicates with customers by using a variety
of online tools (Skype, MSN, Trademanager,Wechat,WhatsAPP ...),
telephone, and e-mail, and adjusts the working hours according to
customer time difference to keep in touch with customers and answer
customer inquiries at any time, customers can use PAYPAL, western
union and other online payment platform to pay a small amount of
sample fee to shorten the sample production time.
