The advantages of reed switches are their small size and light weight, which makes them easy to install and unobtrusive. Due to the small size of the operating switch, no complicated cams or cranks are required, so metal fatigue does not occur and an almost unlimited service life is guaranteed. And can be installed in a limited space, it is suitable for micro devices.
Reed switches and suitable magnets are cheap and easy to obtain. The main reed switch is a non-contact seal switch.
The switch components of the reed switch are sealed in the inert gas and are not in contact with the external environment. This greatly reduces the contact oxidation and carbonization caused by contact sparks during the opening and closing of the contacts. And to prevent external vapor and dust and other impurities on the joint erosion. Long working life.
The reeds are thin and short, have a high natural frequency, increase the speed of the contact on and off, and its switching speed is 5 to 10 times faster than the general electromagnetic relay.
