Hush air switching relay and car braking circuit who has silence effect

The utility model relates to an electron device technical field discloses a hush air switching relay and car braking circuit who has silence effect. In hush air switching relay, connect in parallel through the open type dry reed relay and the closed type dry reed relay that will have the silence effect, can form the conversion type relay that sends of voiceless sound in the course of the work to can satisfy many -sided application, especially the application in car braking circuit. Furthermore, hush air switching relay still has characteristics such as the easy and low in manufacturing cost of dual silence, stable in structure, accessory, be convenient for actual popularization and application. 本实用新型涉及电子器件技术领域，公开了种静音型转换继电器及具有静音效果的汽车刹车电路。在静音型转换继电器中，通过将具有静音效果的常开型干簧继电器和常闭型干簧继电器进行并联，可以形成个在工作过程中无声音发出的转换型继电器,从而可满足多方面的应用，尤其是在汽车刹车电路中的应用。此外，所述静音型转换继电器还具有双重静音、结构稳定、配件容易和制造成本低等特点，便于实际推广和应用。
