接斷(duan)差(cha)(cha)(死區):是指(zhi)開關設定動作值(zhi)和復(fu)位值(zhi)的差(cha)(cha)值(zhi)，例如當(dang)設定、值(zhi)為(wei)1MPa，實際復(fu)位值(zhi)為(wei)0.9MPa時，接斷(duan)差(cha)(cha)為(wei)0.1MPa。

上限(xian)2接點:合(he)并了兩個(ge)上限(xian)形式，分為(wei)分為(wei)兩接點獨立(li)動作(雙(shuang)設定(ding)、雙(shuang)回(hui)路)和兩接點同(tong)時動作(單(dan)設定(ding)、雙(shuang)回(hui)路)兩種類型。

下(xia)限2接點(dian):合并了(le)兩(liang)(liang)個下(xia)限形式(shi)，分為兩(liang)(liang)接點(dian)獨立動作(zuo)(雙(shuang)設(she)定(ding)、雙(shuang)回(hui)路(lu))和兩(liang)(liang)接點(dian)同時(shi)動作(zuo)(單設(she)定(ding)，雙(shuang)回(hui)路(lu))兩(liang)(liang)種類(lei)型。

耐壓:壓力(li)開關保持(chi)其正常(chang)(chang)性能(neng)所能(neng)承受的最(zui)大壓力(li)。但是當壓力(li)開關用于過壓場合時(shi)，敏感元件(jian)將(jiang)會(hui)產生持(chi)續(xu)形變(bian)，這時(shi)壓力(li)設定值(zhi)將(jiang)變(bian)化，壓力(li)開關將(jiang)不能(neng)發揮其正常(chang)(chang)性能(neng)甚至可(ke)能(neng)損壞。

工作(zuo)(zuo)溫(wen)(wen)(wen)(wen)度(du):是指(zhi)儀(yi)器的內部(bu)機構、敏(min)感(gan)元件(jian)(jian)等工作(zuo)(zuo)時不會發生持續變形的溫(wen)(wen)(wen)(wen)度(du)范(fan)圍。一般(ban)壓力開關推薦工作(zuo)(zuo)溫(wen)(wen)(wen)(wen)度(du)范(fan)圍為-5~400C，若介質溫(wen)(wen)(wen)(wen)度(du)過高時，可考慮加附件(jian)(jian)虹吸管(灌狀)，達到降溫(wen)(wen)(wen)(wen)的目(mu)的。
