Abstract

本实用新型涉及一种指南针式电子开关,在指南针的表盘上设置电子开关的正负两极,指针为正、负两级之间的导线,通过改变方向来控制电路开关。

Description

指南针式电子开关
本实用新型涉及一种指南针式电子开关。
目前已有的电子开关中还缺少一种能通过改变方向来控制电路的开关。
本实用新型的目的在于提供一种指南针式电子开关,能够通过改变方向来控制电路的开与关。
本实用新型的目的是以以下方式达到的:
一种指南针式电子开关,其特征在于:在指南针的表盘上设置电子开关的正、负两极,指南针为正、负两极的连接导线。
本实用新型的效果主要是根据指南针无论表盘如何转动而指针始终指向南北两极的原理,通过改变表盘方向来控制电子开关。例如将该开关放在门上,当有人将门打开时,由于门的方向转变,电路便接通,报警器便报警。
图1为本实用新型的俯视图。
图2为本实用新型转动90℃后的俯视图。
本实用新型将结合附图详述如下:图1指南针的表盘1上设有电子开关的正级2和负级3,指针4为正、负极之间的电路导线,将表盘一转动,指针4便将正级2与负级3接通、开关打开。正级2和负级3在指南针的表盘上能够转动,根据人们需要改变方向。
