Relay classified according to the use, must have the automobile relay, communication relay, relay, home machine relay four human, if the contact load classification, mainly has the micro power relay, weak power relays, power relays, power relays in four categories. Relay for electric contactHead material requirements for: excellent electrical conductivity, low and stable contact resistance, good electrical wear resistance and excellent resistance to Soudure {{1}
Istwa a devlopman nan materyèl kontak ak metal pi, depoze antrepriz, poud pou antrepriz la twa koòdone faz . soti nan bon konduktivite tèmik nan antrepriz pi bon pou fè pati nan yon sèl, devlopman nan alyaj la gen bon konduktivite tèmik, ak bon rezistans korozyon ak bon rezistans soude
AGSN02 Kontakte Materyèl Lavi ak Sichuan nan Ewòp te relativman matirite ak lajman ki itilize nan kontakteur, brekè ak relè switch 1, ak nan aspè nan aditif nouvo ak aplikasyon se toujou nan devlopman {{2} Aktyèl sitiyasyon nan aparèy vòltaj ki ba nan peyi Lachin, rechèch la devlope yon materyèl kontak ki koresponn, bay plen jwe nan enstiti rechèch nou an, inivèsite ak antrepriz nan fòs respektif yo, 1 ne ki konsistan, yo nan lòd yo fè AgSno2 materyèl kontak nan peyi nou an popilarite lajè fri yo ta dwe plenn ak pi vit ke posib ak efò
