撥動(dòng)開(kāi)關(guān)的種類(lèi)
來(lái)源: 發(fā)布時(shí)間:2017-07-27 點(diǎn)擊量:1866
撥動(dòng)開(kāi)關(guān)分為:小電流撥動(dòng)開(kāi)關(guān)(右圖),和大電流撥動(dòng)開(kāi)關(guān)(左圖)。小電流撥動(dòng)開(kāi)關(guān)常用在電子玩具,數(shù)碼通訊。大電流一般用在電器,機(jī)械等。
撥動(dòng)開(kāi)關(guān)主要廣泛用于:各種儀器/儀表設(shè)備,各種電動(dòng)玩具,傳真機(jī),音響設(shè)備,醫(yī)療設(shè)備,美容設(shè)備,等其它電子產(chǎn)品領(lǐng)域!
簡(jiǎn)單的說(shuō),撥動(dòng)開(kāi)關(guān)就是通過(guò)撥動(dòng)其執(zhí)行機(jī)構(gòu)(開(kāi)關(guān)柄),來(lái)接通或斷開(kāi)電路。它具有滑塊動(dòng)作靈活、性能穩(wěn)定可靠等特點(diǎn),廣泛應(yīng)用于電器、機(jī)械、通訊、數(shù)字影音、樓宇自動(dòng)化、電子產(chǎn)品中。下面來(lái)具體介紹一下:
1.大電流密封型撥動(dòng)開(kāi)關(guān)
它的額定電流高至5A,且采用環(huán)氧樹(shù)脂密封,故為大電流密封型撥動(dòng)開(kāi)關(guān)。它的端子形式有多種,觸點(diǎn)材質(zhì)有鍍銀、金兩種,開(kāi)關(guān)功能多樣。所以,對(duì)此細(xì)分種類(lèi)較多。廣泛應(yīng)用于電器、機(jī)械中。如1000系列中1203A1CQEB(單極三位)型號(hào),具體參數(shù)及尺寸如下:
SPECIFICATIONS Switch Function SPDT Electrical Ratings 5A @ 120VAC, 28VDC Electrical Life 30,000 cycles typical Contact Resistance < 10 mΩmax initial @ 2-4VDC, 100mA Dielectric Strength 1500Vrms min Insulation Resistance > 100MΩ min Operating Temperature -40°C to 85°C Storage Temperature -40°C to 85°C 2.單側(cè)彈回式表面貼裝型撥動(dòng)開(kāi)關(guān)
執(zhí)行機(jī)構(gòu)的操作在側(cè)面,且引腳為貼片式,故為單側(cè)彈回式表面貼裝型撥動(dòng)開(kāi)關(guān)。廣泛應(yīng)用于通訊、數(shù)字影音中。如MS1257型號(hào),具體參數(shù)及尺寸如下:
SPECIFICATIONS Switch Function SPDT Electrical Ratings 300mA @ 6VDC Electrical Life 10,000 cycles typical Contact Resistance < 50 mΩinitial Dielectric Strength 1000Vrms min Insulation Resistance > 100MΩ min Operating Temperature -40°C to 85°C Storage Temperature -40°C to 85°C 3.4P3T直插式撥動(dòng)開(kāi)關(guān)
觸點(diǎn)形式為4P3T,引腳為直插式。故為4P3T直插式撥動(dòng)開(kāi)關(guān)。4P3T決定了它有8對(duì)引腳,同時(shí),還有兩對(duì)支架,起支撐、固定、接地的作用。廣泛應(yīng)用于樓宇自動(dòng)化、電子產(chǎn)品中。如MS4319L5.5型號(hào),具體參數(shù)及尺寸如下:
SPECIFICATIONS Switch Function 4P3T Electrical Ratings 200mA @ 30VDC Electrical Life 10,000 cycles typical Contact Resistance < 50 mΩinitial Actuation Force 250 +/- 100gF Dielectric Strength 1000Vrms min Insulation Resistance > 100MΩ min Operating Temperature -40°C to 85°C Storage Temperature -40°C to 85°C 4.長(zhǎng)執(zhí)行機(jī)構(gòu)頂撥型撥動(dòng)開(kāi)關(guān)
執(zhí)行機(jī)構(gòu)12mm,且位于開(kāi)關(guān)頂端,故為長(zhǎng)執(zhí)行機(jī)構(gòu)頂撥型撥動(dòng)開(kāi)關(guān)。廣泛應(yīng)用于數(shù)字影音、各種儀器/儀表設(shè)備中。如MS2201L12型號(hào),具體參數(shù)及尺寸如下:
SPECIFICATIONS Switch Function DPDT Electrical Ratings 200mA @ 30VDC Electrical Life 10,000 cycles typical Contact Resistance < 50 mΩinitial Actuation Force 200 +/- 100gF Actuator Travel 4.0 mm total Dielectric Strength 1000Vrms min Insulation Resistance > 100MΩ min Operating Temperature -40°C to 85°C Storage Temperature -40°C to 85°C 以上分類(lèi)基于RIVERSUN (HONG KONG) LTD
