Safety proximity switch

A safety proximity switch comprises a switch body, a limiting frame and a clamping moving assembly. A mounting groove is formed in the wall body; the limiting frame is arranged in the mounting groove;and the switch main body is arranged in the limiting frame through the clamping moving assembly. In the working state, the clamping plate, the first heat conduction piece and the second heat conduction piece position and dissipate heat of the switch main body, so that the switch main body is high in stability, fast in cooling and flexible to use; in the overhauling state, the rear end of the clamping plate moves along the guide block, the limiting frame is pushed to extend out of the wall, the switch body can be taken out, overhauling operation is convenient, daily maintenance of the switch body is facilitated, and the safety of the switch body is further improved. 一种安全型接近开关，包括开关主体、限位框和夹持移动组件；墙体上设置有安装槽；限位框设置在安装槽内；开关主体通过夹持移动组件设置在限位框内部。本实用新型在工作状态下，夹持板、第一导热件和第二导热件对开关主体进行定位及散热，使得开关主体稳定性强，降温快，使用灵活；在检修状态下，夹持板的后端顺着导向块移动
