Abstract:
A silent electromagnetic relay in which a predetermined degree of silencing effect can be maintained regardless of a change to the specification, a higher silencing effect can be obtained at the time of return, the parts control is easy, and the cost of manufacturing is low. A first silent spring is mounted in a position of an inward face of a moving iron to be attracted to an iron core of an electromagnet portion, and an L-shaped moving iron turning based on excitation and demagnetization of the electromagnet portion is housed in a housing that is a resin molded product. Furthermore, a second silent spring for coming in contact with an inner face of the housing is mounted to an outward face of the moving iron and on an opposite side to the first silent spring.
