微動開關(guān)的工作原理

[ 時間:2016-04-28 點擊: ]

分類編輯微動開關(guān),顧名思義,使用很微小的力度的開關(guān)。其觸電間距較小,力矩較大。一般外部有驅(qū)動桿。在尺寸上有小型,超小型,超級小型等。功能上則有防水型。最常見的應(yīng)用就是鼠標(biāo)按鍵了。
1.小型微動開關(guān):
一般尺寸為長27.8寬10.3高15.9,參數(shù)方面又高容量,低負(fù)載等不同變化。如V3系列:
Operating Frequency (mechanical).....120 operations / mim 
Operating Frequency (electrical).....All ratings-10~30 operations / mim 
Contact Resistance (initial).....30m Ω (Max.) 
Insulation Resistance (at 500VDC).....100M Ω (Min.) 
Dielectric Strength (50-60Hz).....1000VAC RMS 
Service Life (mechanical).....Min. 5000000 operations 
Service Life (electrical).....Min. 10000 operations

2.超小型微動開關(guān)
一般尺寸為長19.8寬6.4高10.2,功能上有高精度和高壽命的不同性能。如SM系列:
Operating Frequency (mechanical).....120 operations / mim 
Operating Frequency (electrical).....10~30 operations / mim 
Contact Resistance (initial).....300m Ω (Max.) 
Insulation Resistance (at 500VDC).....100M Ω (Min.) 
Dielectric Strength (50-60Hz).....1000VAC RMS 
Service Life (mechanical).....Min. 10000000 operations 
Service Life (electrical).....Min. 6000 operations


3.超級小型微動開關(guān)
一般尺寸為長12.8寬5.8高6.5,這一型中又有特薄型的設(shè)計。如DF系列
Operating Frequency (mechanical).....120 operations / mim 
Operating Frequency (electrical).....0.1A-120,3A-10~30 operations / mim 
Contact Resistance (initial).....100m Ω (Max.) 
Insulation Resistance (at 500VDC).....100M Ω (Min.) 
Dielectric Strength (50-60Hz).....1000VAC RMS 
Service Life (mechanical).....Min. 1000000 operations 
Service Life (electrical).....3A-Min. 10000 operations

4. 防水型
此類產(chǎn)品其防水級別已達(dá)到IP67,如SW系列:
Operating Frequency (mechanical).....120 operations / mim 
Operating Frequency (electrical).....10~30 operations / mim 
Contact Resistance (initial).....30m Ω (Max.) 
Insulation Resistance (at 500VDC).....100M Ω (Min.) 
Dielectric Strength (50-60Hz).....1000VAC RMS 
Service Life (mechanical).....Min. 2000000 operations 
Service Life (electrical).....Min. 10000 operations
