Reed Switch Device Remains One Of The Most Essential Devices In Electric And Electronic Products

 

Reed Switch Device is a device that functions to detect magnetic intrusion from any magnetic field that is emanating outside the boundaries of its metallic shell. As such, it can be classified as either a switching or relay device. Reed switch device can be fixed to the shafts inside a housing. Hence, it needs to be fixed to the shafts and housing. What is more, if there is any gap, such as a metal shim or a pin, there can be a big risk for the device to get damaged and even for the power circuit to get cut. Therefore, such openings have to be well hidden.

The operating principle of the Reed switch device is based on two principles, namely magnetic contacts that overlap in their space and a small but powerful magnetic field. The device has a pair of magnetic contacts, which are called contact's P-1 and contacts S-1 that are placed at a distance of one meter from the Reed switch housing. The two magnetic contacts P-1 and S-1 are placed on the outer side of the Reed switch housing. These two contacts are located on the top of the switch il and thus, their position will determine the overall height of the Reed switch. On the other hand, the height of the Reed switch housing is pre-determined by the magnetic field that prevails around the Reed switch. Hence, such factors will govern whether the Reed switch ill is exposed to a strong magnetic field or not.

The Reed switch must have a sufficient number of fixed contacts, which are also referred to as a butt engagement, in order to allow the magnetic flux to build up enough magnetic force over a fixed period of time. Butt engagement is defined as the position of the center of mass of the magnetic field that is induced onto the surface of the reeds. Recently, Pickering Electronics, a. U.K.-based reed Switch Company, launched the industry’s smallest high voltage relay named Series 131 reed relays.
