船型介绍:船型开关也称波形开关,其结构与钮子开关相同,只是把钮柄换成船型。船型开关常用作电子设备的电源开关,其触点分为单刀单掷和双刀双掷等几种,有些开关需要带灯还带有指示灯.    应用范围:船型开关应用于饮水机、跑步机、电脑音箱、电瓶车、摩托车、离子电视机、咖啡壶、排插、按摩机等,主要是家用电器之类的用的比较多。    船型开关寿命的测试方法:主要测试开合的次数,直至损坏,如果不用手动可用1个小电机带动偏心开合开关,用计数器记录次数!此开关要求安规认证的,产品在国内销售的话用CQC,国外的话看具体销售去哪一个国家,如美国UL,加拿大CUL,欧洲国家有VDE、ENEC、TUV等安规认证。    船形开关分类:     1. 单刀单掷:1个动触点和1个静触点。只有1通道       2. 单刀双掷:1个动触点和2个静触点,(可分别接通两边的静触点)  3. 双刀单掷,2个动触点和2个静触点,有2个通道       4. 双刀双掷,2个动触点和4个静触点,有4个通道 (可分别接通两边的2个静触点)    船形开关的故障问题:        船形开关内部有一个金属片,中间有弹簧支点,弹簧位移以及塑料支架老化变形,开关就不灵活了,可以断电后拆开来看看,如果不是塑料件损坏,也许可以恢复。开关内部的零线是直通的,与开关部件没有关系,因此有因为开关跳空气开关的话,是经过开关的零线的绝缘层损伤,可以将损伤的一段剪掉重新接线,注意绝缘性要保证。也可能是指示灯的脚有短路,重新接线即可
