Qiyaastii 1880-kii, Edison waxa uu allifay laambad-haystaha iyobeddelo, abuurista taariikhda wax soo saarka furayaasha iyo saldhigyada. Ka dib, injineerka korontada ee Jarmalka Augusta Lausi (ROS. August) ayaa sii soo jeediyay fikradda furayaasha korantada, saldhigyada furaha hore ee wax soo saarku waxay inta badan ku urursan yihiin wadamada horumaray ee Maraykanka iyo Yurub;
Sannadkii 1913kii, Shirkadda General Electric ee Maraykanka waxay bilowday inay soo saarto shiishadaha guryaha ee Shanghai.
Sannadkii 1914kii, Qian Tangsen waxa uu aasaasay warshadda mishiinnada korontada ee Qian Yongji ee Shanghai, Shiinuhuna waxa ay bilaabeen ganacsigooda korontada;
Sannadkii 1916-kii, wax-soo-saarka gudaha ee alaabada beddelka korontada ayaa bilaabmay;
Sannadkii 1919-kii, waxa ay bilaabeen in ay ku daydaan qaar ka mid ah shixnadaha Maraykanka.
Kahor 1949-kii, waxa jiray tiro yar iyo kuwo aad uyar oo soo saara godadka shiinaha, badiyaa soo saara furayaasha taayirrada toosan, furayaasha fidsan, kuwa iftiinka maalintii, furayaasha, saldhigyada laba-isticmaalka, saldhigyada saddexda weji iyo alaab kale.
Waqtigaas, shirkadaha korontada ee dalalka kale ee adduunka ayaa si degdeg ah u horumaray, oo leh tignoolajiyada horumarsan iyo baaxad weyn.
Sannadihii 1980-aadkii, warshadaha dalagga daloolka dalagga ee dalagga ayaa galay xilli cusub oo horumarineed, waxaana si isdaba joog ah loo sameeyay laba saldhig oo wax-soo-saarka dalagga beddelka ah ee Shiinaha oo ku kala yaalla Wenzhou iyo Huizhou, Shunde, iyo Zhongshan. Shiinuhu waxa uu noqday daloolka beddelka ee ugu muhiimsan adduunka. Mid ka mid ah saldhigyada wax soo saarka.
Beddel horumarka caadiga ah
Kahor 1949kii, wax soo saarka korontada ee Shiinaha waxay inta badan ku xirnaayeen soo dejinta. Waqtigaas, ma jirin halbeeg isku mid ah oo loogu talagalay saldhigyada beddelka ee adduunka.
Ka dib 1950, Saldhigga Korantada ee Shanghai ayaa sidoo kale maareeyay tayada warshadaha, taas oo si weyn u dhiirrigelisay jaangooyooyinka alaabta.
Sannadihii 1960-aadkii, Machadka Cilmi-baadhista Qalabka Korontada ee Guangzhou waxa uu aasaasay xarun baadhista walxaha korantada ee dubista gudaha ee qaranka.
Sannadihii 1970-aadkii, shirkii ugu horreeyay ee fiilada bakelite ee gudaha ayaa lagu qabtay Harbin si loo sii habeeyo.
Sannadkii 1966kii, Guddiga Farsamada Farsamada ee Caalamiga ah ayaa soo bandhigay hindise halbeeg oo midaysan.
Sannadkii 1970-kii, Guddiga Farsamada Farsamada ee Caalamiga ah ayaa go'aansaday in ay sameeyaan laan si ay u daraaseeyaan furayaasha iyo saldhigyada, waxayna bilaabeen inay dejiyaan heerarka IEC ee saldhigyada beddelka.
Sanadihii 1970-meeyadii iyo 1980-meeyadii, dalkaygu wuxuu sidoo kale si aayar aayar ah u habeeyey godadka beddelka heer qaran iyo heer caalamiba. Ka dib, Machadka Cilmi-baarista Qalabka Korantada ee Guangzhou ayaa dib u eegis ku sameeyay heerarka daloolka beddelka iyadoo la tixraacayo heerka IEC. Ilaa hadda, dalkeenu dalkeenu waxa uu samaystay nidaam heersare ah oo dhamaystiran.
Beddel qaabdhismeedka kobaca
Kahor 1980-aadkii, furayaasha silig-jiidista ee dusha sare ku rakiban, furayaasha rotary-ga ah, furayaasha badhamada yaryar, iyo saldhigyada dusha sare ku dheggan ayaa si weyn looga isticmaali jiray dalka oo dhan. Mabda'a shaqadu wuxuu ahaa badhanka soo booda, hal cidhif-boodboodka, iwm. Alaabtu asal ahaan waxay ahaayeen koronto. Bur alwaax ah iyo naxaas caadi ah.
Badeecadaha caadiga ah ee laga soo bilaabo bartamihii 1980-meeyadii ilaa dabayaaqadii 1990-meeyadii waxa ay ahaayeen nooca ruxruxa ruxruxa ah, nooca guga oo laba jibbaaran, iwm. Qalabku waxa ay ahaayeen PC ama naylon 66, tin fosfor bronze, iwm. Waxa kale oo loo yaqaan "Suulka Suulka".
Dabayaaqadii 1990-meeyadii, alaabooyinka beddelka ayaa si gaar ah u fiirsaday hagaajinta badbaadada, iyada oo shaqada ilaalinaysa albaabka, iyo agabku inta badan waxa ay ka samaysan yihiin agab PC tayo sare leh iyo xidhiidhyo alloy ah. Qaybta weyn ee "furaha furaha" iyo kantaroolka caqliga leh "smart switch" ayaa soo baxay midba midka kale.
