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KW7、KW8、KW9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
3.超級小型微動開關(guān)（鼠標(biāo)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(jì)。如KW1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
