The high performance Hermetically Sealed Direct Current Electromagnetic Relay is a device used for mechanical transfer of signals. It is suitable where mechanical atmosphere is harsh. Also, it is a very important device in space engineering, such as satellites, rockets and various other ground attachments. This device is an electromagnet switch which consists of two short circuits or changeover contacts. Our Hermetically Sealed Direct Current Electromagnet Relay is suitable in electric circuits with double current which switch off at alternating current voltage at a specific frequency.
