帶開(kāi)關(guān)的插座在現(xiàn)代家居已經(jīng)被大面積運(yùn)用了，不僅方便，還可以為家里節(jié)省電?，F(xiàn)在開(kāi)關(guān)插座廠家就要給大家說(shuō)說(shuō)帶開(kāi)關(guān)的插座都有哪些優(yōu)缺點(diǎn)。帶開(kāi)關(guān)的插座優(yōu)點(diǎn)首先，方便電器的通電和斷電。在沒(méi)有帶開(kāi)關(guān)類型的插座之前，我們所使用的所有插座都是如果要斷電，只能是拔掉插頭。而現(xiàn)在，無(wú)論是通電還是斷電，都不用將插頭拔來(lái)拔去，只需要輕輕按一下開(kāi)關(guān)按鈕全部搞定。第二，保護(hù)電器和插座。一些大功率電器的插頭是不適合經(jīng)常拔插的，因?yàn)轭l繁的拔插容易導(dǎo)致插頭磨損； 5、電氣開(kāi)關(guān)則是一種連接電流和切斷電流的電器附件；插座負(fù)責(zé)電器插頭與電源的連接。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"

質(zhì)量好的墻壁開(kāi)關(guān)插座它的外觀是平整光潔有質(zhì)感的，無(wú)毛刺，它摸起來(lái)應(yīng)該是有韌性的，如果摸起來(lái)較脆較薄的話則說(shuō)明質(zhì)量較差。并且好的開(kāi)關(guān)插座大多選用的是質(zhì)量PC材料，阻燃性能好。墻壁開(kāi)關(guān)插座是強(qiáng)制性都帶安全保護(hù)門，及“CCC”安全認(rèn)證標(biāo)志。通常來(lái)說(shuō)，好的墻壁開(kāi)關(guān)插座不容易被直接取下，我們?cè)诓鹣碌臅r(shí)候需要借助專門的工具才能將它取下來(lái)。我們?cè)谶x購(gòu)時(shí)可以用食指和拇指分別按面蓋的對(duì)角，一端按著不動(dòng)，一端用力往下面壓，如果面蓋不穩(wěn)松動(dòng)，那么開(kāi)關(guān)質(zhì)量比較差。好的滑板式開(kāi)關(guān)在使用時(shí)手感順，聲音輕，節(jié)奏感強(qiáng)。零線直接接入插座3個(gè)孔中的N孔內(nèi)接牢。地線直接接入插座3個(gè)孔中的E孔內(nèi)接牢。成都國(guó)標(biāo)開(kāi)關(guān)插座公牛</p><p

另外，經(jīng)常拔插插頭還容易讓插座的彈片夾頭松動(dòng)，容易導(dǎo)致接觸不良。當(dāng)插座上有了開(kāi)關(guān)后，這些問(wèn)題就通通解決了。帶開(kāi)關(guān)的插座缺點(diǎn)首先，價(jià)格比較高。和一般的插座相比，帶有開(kāi)關(guān)按鈕的插座價(jià)格會(huì)更高。在這一點(diǎn)對(duì)于很多朋友來(lái)說(shuō)都是致命傷，畢竟預(yù)算有限。第二，按鈕容易損壞。當(dāng)插頭不用總是拔來(lái)拔去后，電器的通電和斷電的責(zé)任落在了開(kāi)關(guān)按鈕上。所以，插板上的開(kāi)關(guān)總是被我們反反復(fù)復(fù)地按來(lái)按去，開(kāi)關(guān)也就容易壞掉。當(dāng)開(kāi)關(guān)壞掉后，它也就變成一般的插座了。成都國(guó)標(biāo)開(kāi)關(guān)插座公牛</p></p><br
