Nhanganyaya
Mumidziyo yemagetsi uye masisitimu e otomatiki, ma "micro switch", ane saizi diki uye mashandiro akanaka, ave zvinhu zvakakosha pakuwana kutonga kwakarurama. Rudzi urwu rwe switch runowana kudzora kwakavimbika kwe "circuit on-off" munzvimbo diki kuburikidza nekugadzira kwehunyanzvi hwemakanika uye hunyanzvi hwezvinhu. Hunhu hwayo huri mukubudirira kwetekinoroji ina: nzira yekukurumidza kushanda, kugadzirisa nzvimbo yekubatana, kuvandudza kugara kwenguva refu, uye kudzora arc. Kubva kumabhatani emouse kusvika kumidziyo yemuchadenga, kuvapo kwema "microswitch" kuri kwese kwese. Kusatsiviwa kwavo kunobva mukushandiswa kwakarurama kwemitemo yepanyama uye kutsvaga kwekupedzisira kwekugadzira maindasitiri.
Nzira huru uye zvakanakira tekinoroji
Maitiro ekukurumidza kushanda
Chinhu chikuru che microswitch chiri muchimiro chayo chekukurumidza kushanda, icho chinoshandura masimba ekunze kuita simba re elastic potential retsvimbo kuburikidza nezvikamu zvekutumira zvakaita se levers nema rollers. Kana simba rekunze rasvika pakukosha kwakakosha, tsanga inoburitsa simba ipapo ipapo, ichisundira ma contacts kuti apedzise on-off switching nekumhanya kwe millisecond. Maitiro aya haana chekuita nekumhanya kwesimba rekunze. Kubatsira kwechimiro chekukurumidza kushanda kuri mukuderedza nguva ye arc. Kana ma contacts akaparadzana nekukurumidza, arc haisati yagadzira plasma channel yakagadzikana, nokudaro ichideredza njodzi ye contact ablation. Data rekuyedza rinoratidza kuti quick-acting mechanism inogona kuderedza nguva ye arc kubva pamazana emamiriyoni e switch dzechinyakare kusvika pa 5-15 milliseconds, zvichiwedzera hupenyu hwebasa.
Kugadzira Zvinhu Zvitsva
Kusarudzwa kwezvinhu zvinobata mhepo ndiyo kiyi yekugara kwenguva refu. Zvidimbu zvesirivha zvinoshanda zvakanaka kwazvo mukushandiswa kwemagetsi ane simba rakawanda nekuda kwesimba razvo remagetsi repamusoro uye kuzvichenesa, uye oxide layers dzadzo dzinogona kubviswa nekukanganiswa nemagetsi. Zvidimbu zveTitanium alloy zvinozivikanwa nehuremu hwazvo hwakareruka, simba rakawanda uye kuramba ngura. Maswichi ekuona madivi maviri eALPS anoshandisa titanium alloy reeds, ane hupenyu hwemuchina hunosvika mamiriyoni gumi, zvinova zvakapetwa kashanu pane zvechinyakare zve copper alloy reeds. Ma microswitch ari mumunda wendege anotoshandisa goridhe-plated silver alloy contacts, senge hatch switch yeShenzhou-19, iyo inogona kuramba ichishanda isina mhosva kwemakore makumi maviri pasi pekupisa kwakanyanya kubva pa -80 ℃ kusvika 260 ℃, uye kukanganisa kwekubatana kwekubatana kushoma pane 0.001 seconds.
Mashoko ekubata
Nzvimbo yekubata ye microswitch inowanzogadzirwa pakati pe 0.25 ne 1.8 millimeters. Nzvimbo diki iyi inokanganisa zvakananga kunzwa uye kuvimbika. Tora nzvimbo ye 0.5-millimeter semuenzaniso. Kufamba kwayo kunoda 0.2 millimeters chete kuti itange, uye kushanda kwayo kwekudzivirira kudedera kunowanikwa nekuvandudza zvinhu zvekubata uye chimiro.
Kudzora rusvingo
Kuti idzvinyirire arc, microswitch inoshandisa matekinoroji akasiyana-siyana:
Maitiro ekukurumidza kushanda: Kupfupisa nguva yekuparadzanisa kubatana uye kuderedza kuunganidzwa kwesimba re arc
Chimiro chekudzima arc: Arc inotonhodzwa nekukurumidza kuburikidza nekamuri rekudzima arc receramic kana tekinoroji yekuputira arc yegasi.
Kugadziriswa kwezvinhu: Utsi hwesimbi hunogadzirwa nekubatana kwesirivha nemagetsi esimbi pasi pesimba remagetsi rakawanda hunogona kupararira nekukurumidza, zvichidzivirira kugara kweplasma.
Honeywell V15W2 series yapasa chitupa cheIEC Ex uye yakakodzera nzvimbo dzinoputika. Chimiro chayo chekuvharira uye dhizaini yayo yekudzima arc zvinogona kuita kuti pasave nekubuda arc pamagetsi e10A.
Kushandiswa kweindasitiri uye kusatsiviwa
Zvigadzirwa zvemagetsi zvevatengi
Zvishandiso zvakaita semabhatani emouse, magamepads, uye makhibhodi elaptop zvinoshandisa ma microswitch kuti zviwane mhinduro dzinokurumidza. Semuenzaniso, hupenyu hwe microswitch ye e-sports mouse hunofanira kusvika kanopfuura mamiriyoni makumi mashanu. Zvisinei, Logitech G series inoshandisa modhi yeOmron D2FC-F-7N (20M). Nekugadzirisa kumanikidzwa kwekubatana uye stroke, inoita kuti kunonoka kwe trigger kusvike 0.1 milliseconds.
Maindasitiri neMotokari
Mukushanda kwemaindasitiri, ma microswitch anoshandiswa pakuisa majoini emaoko emakanika, kudzikamisa mabhandi ekufambisa uye kudzora magonhi ekuchengetedza. Mubasa remotokari, rinoshandiswa zvakanyanya mukuisa airbag, kugadzirisa zvigaro uye kuona magonhi. Semuenzaniso, microswitch yemusuwo weTesla Model 3 inoshandisa dhizaini isingapindi mvura uye inogona kushanda zvakadzikama munzvimbo inotangira pa -40 ℃ kusvika 85 ℃.
Hutano neNdege
Zvishandiso zvekurapa zvakaita semaventilator nemamonitor zvinoshandisa microswitches kuti zvigadziriswe uye alarm yekukanganisa. Kushandiswa kwaro munzvimbo yendege kunotoda simba rakawanda. Microswitch yemusuwo wekamba yendege yeShenzhou inofanira kupasa bvunzo dze vibration, shock uye salt spray. Chivharo chayo chesimbi yese uye dhizaini yayo inodzivirira kupisa zvinovimbisa kuchengetedzeka kwakakwana munzvimbo yemuchadenga.
Mhedziso
"Simba guru" rema microswitches rinobva mukubatanidzwa kwakadzika kwemitemo yemakanika, sainzi yezvinhu uye maitiro ekugadzira. Kuburitswa kwesimba nekukurumidza kwesimba rinoshanda nekukurumidza, kunyatsojeka kwe micron-level kwenzvimbo yekubatana, kubudirira mukugara kwenguva refu kwezvinhu zve titanium alloy, uye dziviriro yakawanda yekudzora arc zvinoita kuti zvisatsiviwe mumunda wekudzora kwakarurama. Nekufambira mberi kwehungwaru uye otomatiki, ma microswitches ari kukura akananga ku miniaturization, kuvimbika kwakanyanya uye kushanda kwakawanda. Mune ramangwana, achaita basa rakakura muminda yakaita semotokari itsva dzesimba, marobhoti eindasitiri uye ndege. Ichi chikamu "chidiki, simba guru" chinoramba chichitungamira kutsvaga kwevanhu miganhu yekururamisa kwekudzora.
