tri-metal composite button contact widely used in micro switches and breakers protector
Specifications
3. Characteristics
A) Silver graphite contact has a good performance in resistance to
contact wedding, low contact resistance and high arc erosion
resistance
B) AgWC contact is very hard and sufficient mechanical strength,
during arcing a protective gas layer of CO is formed which limits
the reaction of oxygen on the contact surface and therefore the
formation of metal oxides

4. Applications
AgW, CuW, AgWC contacts choose different powder materials with
adding inside Ni, Co mineral and by using pre-sinter and active
sinter technology then improve their consistency and ameliorate
electrical function of contact materials. Mainly used in middle and
large capacity relay, contactor, middle and small capacity low
voltage breaker, DC/AC switch, drive protective switch, creepage
protective switch etc.
Their applications as follows:
A) AgC series
Mainly used in protective switch such as miniature breaker,
creepage protective switch or motor protective switch with coupling
contact in AgW.
B) CuW series
Widely used in high voltage breaker.
C) AgWCAgWCC series
Mainly used in high electricity charge switchgear such as breaker,
creepage switch. Generally they are used with AgNi ,AgWC together.
D) AgNi series
Widely used in DC/AC relay, designation switch, contactor, light
switch, thermal controller, timer of washer etc.
E) AgNiC series
Widely used in omnipotence breakers such as DW45 intelligence
coupling with AgW.
F) AgW series
All kinds of omnipotence breakers, plastic breakers, heavy charge
AC/DC contactorother switches.
G) Silver oxidized metal series
Mainly used in wasser mengen in relay,contactor, small and
medium-sized capacity and DC low voltage circuit breaker switch
powder protection switch and leakage protection switch,etc.
