Problems solved by technology
[0002] Most of the existing balanced force relay contact functions only have switching functions or only have the functions of moving and breaking. With the needs of scientific research and production of weapons and equipment, a balanced force electromagnetic relay with moving and switching functions is needed. , but due to the structural characteristics of the balanced force electromagnetic relay, there is no moving part in the contact system, and the moving reed moves with the armature, so it can only achieve a single function, and cannot satisfy the moving and switching functions at the same time. Therefore, it is necessary to develop a Balanced Force Electromagnetic Relay with Switching and Switching Functions
