最簡(jiǎn)單的開(kāi)關(guān)有二片名叫“觸點(diǎn)”的金屬，二觸點(diǎn)接觸時(shí)使電流形成回

 路，二觸點(diǎn)不接觸時(shí)電流開(kāi)路。選用接點(diǎn)金屬時(shí)需考慮其對(duì)抗腐蝕的程度，因?yàn)榇蠖鄶?shù)金屬氧化后會(huì)形成絕緣的氧化物，使接點(diǎn)無(wú)法正常工作。選用接點(diǎn)金屬也需考慮其電導(dǎo)率、硬度、機(jī)械強(qiáng)度、成本及是否有毒等因素。有時(shí)會(huì)在接點(diǎn)上電鍍抗腐蝕金屬。一般會(huì)鍍?cè)诮狱c(diǎn)的接觸面，以避免因氧化物而影響其性能。有時(shí)接觸面也會(huì)使用非金屬的導(dǎo)電材料，如導(dǎo)電塑膠。開(kāi)關(guān)中除了接點(diǎn)之外，也會(huì)有可動(dòng)件使接點(diǎn)導(dǎo)通或不導(dǎo)通，開(kāi)關(guān)可依可動(dòng)件的不同為分為杠桿開(kāi)關(guān)（Toggle switch）、按鍵開(kāi)關(guān)、船型開(kāi)關(guān)（Rocker switch）等，而可動(dòng)件也可以是其他型式的機(jī)械連桿。
