Cha m'ma 1880, Edison anapanga choyikapo nyali ndikusintha, kupanga mbiri ya kupanga masiwichi ndi zitsulo.Kenako, German magetsi injiniya Augusta Lausi (ROS. August) anapitiriza maganizo mfundo masiwichi magetsi, oyambirira lophimba matako Opanga makamaka anaikira m'mayiko otukuka mu United States ndi Europe;
Mu 1913, General Electric Company ya ku United States inayamba kupanga zosinthira zowunikira kunyumba ku Shanghai.
Mu 1914, Qian Tangsen anakhazikitsa Qian Yongji Electrical Machinery Factory ku Shanghai, ndipo a China anayamba bizinesi yawo yamagetsi;
Mu 1916, kupanga zoweta zamagetsi zosinthira magetsi kunayamba;
Mu 1919, anayamba kutsanzira masiwichi ena aku America.
Chaka cha 1949 chisanafike, panali opanga ochepa komanso ang'onoang'ono a sockets ku China, makamaka kupanga masiwichi opingasa gudumu, masiwichi athyathyathya, masiwichi a masana, mapulagi, zitsulo zapawiri, zoyambira magawo atatu ndi zinthu zina.
Panthawiyo, makampani opanga magetsi m'mayiko ena padziko lapansi adakula mofulumira, ndi luso lamakono komanso lalikulu.
M'zaka za m'ma 1980, msika wa dziko langa wosinthira khoma unalowa m'nthawi yatsopano yachitukuko, ndipo zoyambira ziwiri zaku China zosinthira socket zokhala ku Wenzhou ndi Huizhou, Shunde, ndi Zhongshan zidapangidwa motsatizana.China yakhala socket yofunika kwambiri padziko lonse lapansi.Chimodzi mwazinthu zopangira.
Sinthani masinthidwe okhazikika
Chaka cha 1949 chisanafike, zinthu zamagetsi zaku China zinkadalira kwambiri zogulitsa kunja.Pa nthawiyo, panalibe muyezo wofanana wa sockets padziko lapansi.
Pambuyo pa 1950, Shanghai Power Station inayendetsanso khalidwe la mafakitale, lomwe limalimbikitsa kwambiri kukhazikika kwa zinthu.
M'zaka za m'ma 1960, bungwe la Guangzhou Electrical Apparatus Research Institute linakhazikitsa malo oyesa magetsi a bakelite m'nyumba.
M'zaka za m'ma 1970, msonkhano woyamba wa bakelite wamkati unachitikira ku Harbin kuti apititse patsogolo.
Mu 1966, International Electrotechnical Commission idakhazikitsa njira yogwirizana.
Mu 1970, International Electrotechnical Commission idaganiza zokhazikitsa nthambi kuti iphunzire mapulagi ndi zitsulo, ndipo idayamba kukhazikitsa miyezo ya IEC yosinthira masinthidwe.
M'zaka za m'ma 1970 ndi 1980, dziko langa linasinthanso pang'onopang'ono masinthidwe kudziko lonse lapansi komanso padziko lonse lapansi.Pambuyo pake, bungwe la Guangzhou Electrical Apparatus Research Institute linasinthanso masinthidwe a socket potengera muyezo wa IEC.Pakali pano, dziko lathu khoma lophimba zitsulo wapanga ndi wathunthu muyezo dongosolo.
Kusintha kwa kamangidwe
Zaka za m'ma 1980 zisanafike, ma switch-waya okwera pamwamba, ma rotary switch, ma switch osinthira, mabatani ang'onoang'ono, ndi ma soketi okwera pamwamba anali kugwiritsidwa ntchito kwambiri m'dziko lonselo.Mfundo yogwirira ntchito inali batani pop-up, single-pole flip-up, etc. Zidazo zinali zamagetsi.Ufa wamatabwa ndi mkuwa wamba.
Zogulitsa zodziwika bwino kuyambira m'ma 1980 mpaka kumapeto kwa zaka za m'ma 1990 zinali zoyenda za rocker, rocker yamtundu wapawiri, etc. Zidazo zinali PC kapena nayiloni 66, tin phosphor bronze, etc., chifukwa mawonekedwe ake anali ang'onoang'ono batani. imatchedwanso "Thumb switch".
Chakumapeto kwa zaka za m'ma 1990, zinthu zosinthira zidapereka chidwi kwambiri pakuwongolera chitetezo, ndi ntchito yoteteza chitseko, ndipo zidazo zidapangidwa makamaka ndi zida zapa PC zapamwamba komanso kulumikizana kwa aloyi.Gulu lalikulu la "key switch" ndi "smart switch" yowongolera mwanzeru idatuluka.
