Abstract:
A sealed contact device capable of maintaining a function for drawing a generated arc to disappear rapidly and reliably for a long period. An electromagnetic relay includes a housing, a stationary contact and a moving contact which are disposed opposite to each other in the housing, and a pair of permanent magnets and disposed opposite to the stationary contact and the moving contact. An arc generated between the stationary contact and the moving contact is drawn due to a current conducting between the stationary contact and the moving contact and magnetic forces of the permanent magnets. An arc shield member is disposed in a position in which an arc in the housing is induced.
