PCB membrane switch
PCB membrane switch zvinoreva kuti pateni uye dunhu rekuchinja rinogadzirwa pane yakajairwa yakadhindwa yedunhu copper clad board.
Chimiro chePCB membrane switch ndechekuti zvinhu zviri nyore kushandisa, maitiro akagadzikana, kushorwa kwakadzikira, uye zvimwe zvikamu zvedunhu zvinogona kusungirirwa zvakananga kuseri kwePCB.Kana iri nzvimbo duku, iyo yakaoma liner layer inogona kusiyiwa.PCB inogona kugadzirwa nehupamhi hwe 0.5mm-3.0mm.
PCB membrane switch kazhinji inoshandisa simbi madhairekitori se conductive labyrinth contacts, saka ivo vanonzwa zviri nani.Izvo zvakashata ndezvekuti hazvina kunaka sekuchinjika membrane switch yekumisikidza uye kubatanidza mumushini wese, uye kazhinji zvinodiwa weld yekubatanidza uye kutungamira inotungamira kuburikidza netambo tambo.Pamusoro pechiratidzo chebuzzer uye chiratidzo che LED, iyo mhinduro yeruzivo yeiyo yakasimba membrane switch inogona kazhinji kushandisa simbi mubato shrapnel.
