Co je na n\u011bm tak zvl\u00e1\u0161tn\u00edho?\tAbychom mohli na tuto ot\u00e1zku odpov\u011bd\u011bt, mus\u00edme si nejprve \u0159\u00edci, na jak\u00e9m principu vlastn\u011b funguje a k \u010demu p\u0159esn\u011b slou\u017e\u00ed. Dobr\u00e9 je si tak\u00e9 \u0159\u00edci, kde v\u0161ude se s n\u00edm m\u016f\u017eeme vlastn\u011b setkat.\tCo je to tedy vyp\u00edna\u010d? Zjednodu\u0161en\u011b \u0159e\u010deno se jedn\u00e1 o za\u0159\u00edzen\u00ed, kter\u00e9 n\u00e1m umo\u017e\u0148uje uv\u00e1d\u011bt do chodu nebo naopak zastavovat nejr\u016fzn\u011bj\u0161\u00ed p\u0159\u00edstroje. T\u00edm asi nejpou\u017e\u00edvan\u011bj\u0161\u00edm, kter\u00fd se vybav\u00ed nejsp\u00ed\u0161 ka\u017ed\u00e9mu z n\u00e1s p\u0159i vysloven\u00ed tohoto slova, je ten od stropn\u00edho osv\u011btlen\u00ed. Zvl\u00e1\u0161t\u011b v zim\u011b jej pou\u017e\u00edv\u00e1me n\u011bkolikr\u00e1t denn\u011b, \u010dasto ani\u017e si to uv\u011bdomujeme.\tJak ale funguje? Nejprve je t\u0159eba rozli\u0161it dva typy, mechanick\u00fd a elektrick\u00fd. Ten elektrick\u00fd najdeme v ji\u017e zm\u00edn\u011bn\u00e9m stropn\u00edm osv\u011btlen\u00ed, ale tak\u00e9 prakticky ve v\u0161ech p\u0159\u00edstroj\u00edch, od po\u010d\u00edta\u010de p\u0159es mikrovlnnou troubu po televizi \u010di pra\u010dku. Principem zde je spojen\u00ed \u010di rozpojen\u00ed kontakt\u016f, co\u017e umo\u017e\u0148uje tok elekt\u0159iny do ur\u010dit\u00fdch \u010d\u00e1st\u00ed p\u0159\u00edstroje, nebo jej naopak blokuje.\tPokud jde o ty mechanick\u00e9, tak ty najdeme nap\u0159\u00edklad ve vodovodn\u00ed baterii \u010di v kohoutc\u00edch u plynov\u00e9ho spor\u00e1ku nebo trouby. Funguj\u00ed podobn\u011b jako v\u00fdpust. Je k nim p\u0159id\u011blan\u00e1 p\u0159ep\u00e1\u017eka, kter\u00e1 nedovol\u00ed vod\u011b \u010di plynu proudit. P\u0159i oto\u010den\u00ed se zvedne a \u010d\u00edm v\u00edce je otev\u0159en\u00e1, t\u00edm v\u00edce tekutiny \u010di plynu m\u016f\u017ee proudit.\t\tK \u010demu tedy slou\u017e\u00ed? Jeho prim\u00e1rn\u00edm \u00fakolem je umo\u017enit n\u00e1m vypnout \u010di uv\u00e9st do chodu ur\u010dit\u00e1 za\u0159\u00edzen\u00ed. Bez n\u011bj by musela b\u011b\u017eet neust\u00e1le, co\u017e by nejen zna\u010dn\u011b zv\u00fd\u0161ilo n\u00e1klady na elekt\u0159inu, ale u n\u011bkter\u00fdch v\u011bc\u00ed, jako je nap\u0159\u00edklad stropn\u00ed osv\u011btlen\u00ed \u010di pra\u010dka, by to bylo prakticky nemo\u017en\u00e9. Koneckonc\u016f, jen m\u00e1lokdo z n\u00e1s je schopen sp\u00e1t p\u0159i rozsv\u00edcen\u00e9m sv\u011btle.\tJak je vid\u011bt, vyp\u00edna\u010d n\u00e1m prokazuje mnoho slu\u017eeb. I proto by si zaslou\u017eil v\u011bt\u0161\u00ed pozornost, ne\u017e se mu nyn\u00ed dost\u00e1v\u00e1.
