Abstract

一种双控联动触点开关,包括有壳体,其特征在于壳体具有两个相互间隔的腔室,在每个腔室内各设置有一套触点开合及其复位机构,一按钮横跨所述的二个腔室,其顶部凸出于壳体之外,在壳体内的部分则同时对准所述二个触点开合及其复位机构的起始动触片。与现有技术相比,本实用新型把二个开关合并成一个开关且共用一个开关按钮,因此保证了用一个开关按钮同时操作两对开关触点,即使开关操作零件有所变形或误差也不会影响开关的同时动作。

Description

双控联动触点开关
本实用新型涉及一种触点开关,特别是指一种双控联动触点开关。
触点开关属于按钮开关,一般分为常开开关和常闭开关,再某些领域,工作时需要同时分别打开二个触点开关,如属于电动工具系列的电动修枝剪在操作过程中,为符合瞬间制动的安全要求,就必须在电路***中并联使用两个开关,操作时,两个开关有次序地先后合上或同时合上,反之,当断开开关时,两个开关在0.5秒内按合上时的相反次序先后断开,或同时断开;由于开关零件一般都由塑料制成的,大批量生产过程中,变形、误差较大,作用在两个开关各自按钮的力变化较大,导致开关合上或断开次序不能可靠保证,更难达到同时断开或合上,最终导致工具失效。
本实用新型的目的就在于针对上述现有技术现状而提供一种可保证二个独立的触点开关同时动作的双控联动触点开关。
本实用新型的目的是这样实现的:双控联动触点开关包括有壳体,其特征在于壳体具有两个相互间隔的腔室,在每个腔室内各设置有一套触点开合及其复位机构,一按钮横跨所述的二个腔室,其顶部凸出于壳体之外,在壳体内的部分则同时对准所述二个触点开合及其复位机构的起始动触片。
与现有技术相比,本实用新型把二个开关合并成一个开关且共用一个开关按钮,因此保证了用一个开关按钮同时操作两对开关触点,即使开关操作零件有所变形或误差也不会影响开关的同时动作。
附图说明:
图1为本实用新型实施例的外观结构示意图。
图2为图1的A向视图(去掉壳体前盖)。
图3为图2的B-B剖视图。
以下结合附图实施例对本实用新型作进一步详细描述。
如图1~图3所示,双控联动触点开关的壳体由前盖11、前壳体12和后壳体13构成,前壳体12与后壳体13各自具有相互间隔的腔室,其内各设置有一套触点开合及其复位机构,由动触片31、簧片32、上静触片33、下静触片34及中脚35构成,其中动触片31末端的动触点位于上静触片33和下静触片34之间,簧片32对动触片31起支撑复位作用,动触片31的另一端则位于横跨前后壳体的按钮2之下,此情形在后壳体内也是如此,参见图2。
