【技术实现步骤摘要】
一种用于电动工具的交流开关
本技术涉及一种开关,尤其是涉及一种用于电动工具的交流开关。
技术介绍
市面上大多数的电动工具都是直接接入交流电,目前,现有技术的交流电开关一般都为图1的结构,动触片的触点与定触片的触点相接触时,触点会粘合在一起,这样结构的开关在断开时都是通过连连杆带动动触片架来进行分离,实际使用过程中,动触片的触点还是容易继续粘合在定触片的触点上,单单靠动触片架的拉力不足以将粘合的触点很好地分开。
技术实现思路
针对现有技术的不足,本技术提供一种用于电动工具的交流开关,结构简单,装配合理,在连杆内部设置弹簧,弹簧可以驱动滑块运动,当触点粘合时,连杆内的弹簧的弹力会强加到触点上,使粘合的触点分离。本技术解决其技术问题所采用的技术方案是:一种用于电动工具的交流开关,包括基座、连杆、动触片和定触片,所述定触片固定在所述基座上,还包括滑块,所述动触片设置在所述滑块上,所述滑块套设在所述连杆的下部,所述连杆驱动所述滑块向下来带动所述动触片与所述定触片接触,所述连杆内设有空腔,所述空腔的上下两端设 ...
