Product Description

28mm Silver Reed Switches are also known as glass tube switches that are greatly admired for having no wear & tear during their operation. These are generally used to control fluctuating current in the reed relays and various sensor based security devices & home appliances. They are controlled by invisible magnetic fields and are known to have longer operational life. 28mm Silver Reed Switches comprise two ferromagnetic contacts that have a gap between them when they are off.



  • No supply voltage required
