?市場上主要開關(guān)品牌一般選用PC料，PC料又叫防彈膠，抗沖擊、耐高溫、不易變色的特性對于控制電氣的開關(guān)來說很重要。比較好的開關(guān)正面面板和背面的底座都是用PC料的，而一般的開關(guān)會在底座上用黑色的尼龍料替換PC料，這樣成本就能降低很多同樣用PC料，很多開關(guān)廠家用的是海內(nèi)產(chǎn)的（就算標(biāo)用的是美國GE什么的其實(shí)也是海內(nèi)合作廠做的，只是由GE賣而已），而目前國內(nèi)其實(shí)還沒有一家公司有能力生產(chǎn)PC料，所謂國內(nèi)產(chǎn)的一般都是用回料重新加工出來的，因而雜質(zhì)比較高，會很脆，耐熱性也明顯不佳。較差的開關(guān)為降低成本正面面板都可能不用PC料，用混合料或ABS替代。這些材料不僅抗沖擊、耐熱性差，還容易變色、表面摸多了就顯得很毛糙。就是開關(guān)過程中導(dǎo)電零件的接觸點(diǎn)。觸點(diǎn)一要看大?。ㄔ酱笤胶茫?，二要看材料。觸點(diǎn)目前主要有三種，銀鎳合金、銀鎘合金和純銀。銀鎳合金是目前比較理想的觸點(diǎn)材料，導(dǎo)電性能、硬度比較好，也不容易氧化生銹。銀鎘合金觸點(diǎn)其他方面也都比較好，但就是鎘元素屬于重金屬，一方面對人體有害，另一方面和銀的融合性也不太理想，會在觸點(diǎn)表面形成鎘金屬小顆粒，導(dǎo)電時可能拉出電弧。純銀做觸點(diǎn)其實(shí)并不合適，導(dǎo)電性能的確不錯，但純銀質(zhì)地比較軟、還很容易氧化（像銀首飾時間一長就會變黑）。質(zhì)地軟，開關(guān)多了觸點(diǎn)就變形了；氧化生銹的話導(dǎo)電性能會差很多，銹點(diǎn)還容易發(fā)熱，很容易就把觸點(diǎn)燒化了?，F(xiàn)在主要都是大面板式的，外觀和手感都比以前拇指式的要好。拇指式的最大的問題在于容易卡住，因?yàn)榱乇容^短，開關(guān)動作幅度比較小，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）出了個所謂復(fù)位開關(guān)，試試手感暴澀，拆開一看里面是一個小滾輪，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，這個開關(guān)該怎么用啊。
