家用墻壁開關(guān)的原材料和元器件的吸濕度都很小，而且不能使用含有棉、麻、絲等的易發(fā)霉物質(zhì)。它的開關(guān)面板采用的耐蝕材料，由于開關(guān)面板直接暴露在空中，所以外頂部采用了平滑設(shè)計(jì)，避免了積水而導(dǎo)致的腐蝕。家用墻壁開關(guān)插座的電子設(shè)備和其它零部件過鍍、涂或化學(xué)處理，表面覆蓋了一層保護(hù)膜，保護(hù)開關(guān)不會受周圍介質(zhì)的影響，而且它的印制板和組件表面涂上了三防清漆，確保了導(dǎo)線之間不會出現(xiàn)電暈和擊穿。另外電感和變壓器也進(jìn)行封端和浸漆，避免了潮氣進(jìn)入而出現(xiàn)短路的情況。以上就是對三防設(shè)計(jì)簡單的一個(gè)介紹，大家只需要了解下就可以。在市場中，大多數(shù)墻壁開關(guān)插座都是擁有三防設(shè)計(jì)的，但是也不排除有個(gè)別，所以當(dāng)我們在購買時(shí)候，還是需要注意下這點(diǎn)的。四川原裝開關(guān)插座廠家直銷火線接入開關(guān)2個(gè)孔中的一個(gè)A標(biāo)記，再從另一個(gè)孔中接出絕緣線接入下面的插座3個(gè)孔中的L孔內(nèi)接牢。</p><div

做好墻壁開關(guān)插座的定期檢查：安裝久的線路可能會出現(xiàn)老化的現(xiàn)象，盡可能的做好定期檢查，保證電線能夠安全輸電，進(jìn)而確保開關(guān)的正常工作；損壞的插頭要做到在專業(yè)人士的幫助下及時(shí)進(jìn)行更換，避免插頭的短路，造成火災(zāi)；插座的使用一定要選對，由于家用電器的功率大小不同，如果電器的電壓與86墻壁開關(guān)插座的功率不同，會造成插座溫度過高，容易燒毀開關(guān)插座。以上就是墻壁開關(guān)插座需要注意的安全弊端，用電安全問題很大，我們在使用電器一定要注意把安全弊端防范于未然。

1、高度：電源開關(guān)離地面一般在120厘米至135厘米之間（一般開關(guān)高度是和成人的肩膀一樣高）視聽設(shè)備、臺燈、接線板等的墻上插座一般距地面30厘米（客廳插座根據(jù)電視柜和沙發(fā)而定），洗衣機(jī)的插座距地面120厘米至150厘米，電冰箱的插座為150厘米至180厘米，空調(diào)、排氣扇等的插座距地面為190厘米至200厘米;廚房功能插座離地110高，間距60放1只歐式脫排位置一般相宜于縱坐標(biāo)定在離地2200mm，橫坐標(biāo)可定吸煙機(jī)本身左右長度的中間，這樣不會使電源插頭和脫排背墻部分相碰，插座位于脫排管道中心；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。</p><div

開關(guān)插座就是安裝在墻壁上使用的電器開關(guān)與插座，是用來接通和斷開電路使用的家用電器，有時(shí)可以為了美觀而使其還有裝飾的功能。開關(guān)有雙控和單控的區(qū)別，雙控每個(gè)單元比單控多一個(gè)接線柱。一個(gè)燈在房里可以控制，在房外也可以控制稱作雙控，雙控開關(guān)可以當(dāng)單控用，但單控開關(guān)不可以作雙控。，按開關(guān)的啟動(dòng)方式來分：拉線開關(guān)、旋轉(zhuǎn)開關(guān)、倒扳開關(guān)、按鈕開關(guān)、蹺板開關(guān).觸摸開關(guān)等，按開關(guān)的連接方式來分：單控開關(guān)、雙控開關(guān)、雙極(雙路)雙控開關(guān)等。增設(shè)防雷功能，保護(hù)生命安全。四川國標(biāo)開關(guān)插座總經(jīng)銷</p><p

3、第三看結(jié)構(gòu)吧。主要都是大面板式的，外觀和手感都比以前拇指式的要好。拇指式的比較大的問題在于容易卡住，因?yàn)榱乇容^短，開關(guān)動(dòng)作幅度比較小，彈簧輕微軟一點(diǎn)或過硬一點(diǎn)，都可能造成開關(guān)卡住。前兩天看到格雷（別跟我說它是米國的，它要是米國的那我就是火星人）出了個(gè)所謂復(fù)位開關(guān)，試試手感暴澀，拆開一看里面是一個(gè)小滾輪，按一下轉(zhuǎn)1/4圈，為減少不可避免的摩擦，上面涂滿了潤滑油。試想半年后里面潤滑油干了，這個(gè)開關(guān)該怎么用啊。四川原裝開關(guān)插座廠家直銷</p></p><br
