style="text-indent:25px">磁性開關(guān)是一種利用磁場(chǎng)信號(hào)來控制的線路開關(guān)器件，也叫磁控開關(guān)。磁性開關(guān)意思就是通過磁鐵來感應(yīng)的，這個(gè)“磁”就是磁鐵，磁鐵也有好幾種，市場(chǎng)上面常用的磁鐵有橡膠磁、永磁鐵氧體、燒結(jié)釹鐵硼等。開關(guān)就是干簧管了。干簧管是干式舌簧管的簡(jiǎn)稱，是一種有觸點(diǎn)的無源電子開關(guān)元件，具有結(jié)構(gòu)簡(jiǎn)單，體積小便于控制等優(yōu)點(diǎn)，其外殼一般是一根密封的玻璃管，管中裝有兩個(gè)鐵質(zhì)的彈性簧片電板，還灌有惰性氣體。平時(shí)，玻璃管中的兩個(gè)由特殊材料制成的簧片是分開的。當(dāng)有磁性物質(zhì)靠近玻璃管時(shí)，在磁場(chǎng)磁力線的作用下，管內(nèi)的兩個(gè)簧片被磁化而互相吸引接觸，簧片就會(huì)吸合在一起，使結(jié)點(diǎn)所接的電路連通。外磁力消失后，兩個(gè)簧片由于本身的彈性而分開，線路也就斷開了。巴士德溫度開關(guān)</p><div

①限位開關(guān)：也可以叫行程開關(guān)；可以安裝在相對(duì)靜止的物體(如固定架、門框等，簡(jiǎn)稱靜物)上或者運(yùn)動(dòng)的物體（如行車、門等）上。當(dāng)物體接近靜物時(shí)，開關(guān)的連桿驅(qū)動(dòng)開關(guān)的接點(diǎn)引起閉合的接點(diǎn)分?jǐn)嗷蛘邤嚅_的接點(diǎn)閉合。由開關(guān)接點(diǎn)開、合狀態(tài)的改變?nèi)タ刂齐娐泛蜋C(jī)構(gòu)的動(dòng)作。 ②接近開關(guān)：一種無需與運(yùn)動(dòng)部件進(jìn)行機(jī)械直接接觸而可以操作的檢測(cè)位置的傳感器，接近開關(guān)又稱無觸點(diǎn)行程開關(guān)，它可以完成行程控制和限位保護(hù)等。該傳感器無需與檢測(cè)物質(zhì)接觸，但是檢測(cè)物質(zhì)的材質(zhì)需要是金屬，因?yàn)闊o需與檢測(cè)接觸，因此它的特點(diǎn)是工作可靠、壽命長(zhǎng)、功耗低、復(fù)定位精度高、操作頻率高以及適應(yīng)惡劣的工作環(huán)境等。 ③光電開關(guān)；它是利用被檢測(cè)物對(duì)光束的遮擋或反射，由同步回路接通電路，從而檢測(cè)物體的有無。物體不限于金屬，所有能反射光線（或者對(duì)光線有遮擋作用）的物體均可以被檢測(cè)。</p><p style="text-indent:25px">壓力開關(guān)的工作原理是如果壓力開關(guān)系統(tǒng)里面的壓力高于或者是比初始設(shè)定的安全的壓力值小的話，壓力開關(guān)里面的感應(yīng)器里面的碟片可以及時(shí)地感應(yīng)到并且發(fā)生警報(bào)，同時(shí)會(huì)發(fā)生移動(dòng)，通過和導(dǎo)桿相互連接，使得壓力開關(guān)的接頭接通電源或者是和電源相互斷開。當(dāng)壓力開關(guān)系統(tǒng)里面的壓力恢復(fù)到初始設(shè)定的安全壓力值的時(shí)候，碟片又可以及時(shí)地感應(yīng)到，然后在一瞬間恢復(fù)到原位，開關(guān)也會(huì)自動(dòng)恢復(fù)到原來的位置和狀態(tài)。但需要注意的是，選擇壓力開關(guān)的時(shí)候必須了解壓力開關(guān)的壓力有沒有脈動(dòng)，需不需要用到節(jié)流閥這種會(huì)對(duì)儀表有所損失的儀器。</p><div
