微动开关分类
微动开关,顾名思义,使用很微小的力度的开关。其触电间距较小,力矩较大。一般外部有驱动杆。在尺寸上有小型,超小型,超级小型等。功能上则有防水型。最常见的应用就是鼠标按键了。
1.小型微动开关:
一般尺寸为长27.8宽10.3高15.9,参数方面又高容量,低负载等不同变化。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
2.超小型微动开关
一般尺寸为长19.8宽6.4高10.2,功能上有高精度和高寿命的不同性能,如KW11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.超级小型微动开关(鼠标微动开关)
一般尺寸为长12.8宽5.8高6.5,这一型中又有特薄型的设计。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
