Description

电路密码开关
技术领域
本实用新型涉及电器开关领域的一种电路密码开关。
背景技术
一些特殊场合的电器需要专人操作控制,通常的做法是采用电子密码锁的形式控制专用电器的供电电源,但是电子密码锁在使用过程中普遍存在的问题是容易出现掉电现象,这样就失去控制作用,并且电子密码锁电路复杂,成本高,容易出故障。
发明内容
本实用新型的目的就是针对现有技术存在的缺陷,提供一种结构简单、操作方便、稳定使用的电路密码开关。
其技术方案是:由2只或2只以上的扭子开关串联逻辑组合成2的平方数种状态的一种连接方式。
本实用新型具有结构简单、加装方便,安装在需要的电器电源前,可有效的防止某些贵重仪器被他人使用。
附图说明
附图是一种实施例的电路原理图。
具体实施方式
图中CZ是用电器插座;CT是电源插头;K1-K6是扭子开关。电源插头CT、钮子开关K1-K6和用电器插座CZ串联组成。只有K1下扳、K2上扳、K3、K4、K5下扳、K6上扳的情况下,用电器插座CZ才会有电,K1-K6中只要扳错一只,则用电器插座CZ不会有电。改变连接线路可改变密码组合方式。
