摘要:
Provided is an electromagnetic relay which does not require a braided wire for securing a current capacity of a main contact unit. The electromagnetic relay includes a main contact unit inserted into a power supply path to a load and an arc contact unit connected in parallel to the main contact unit. An auxiliary contact unit is electrically independent of the main contact unit and the arc contact unit. The main contact unit includes a main fixed contact fixed to a frame body and a main contact spring made of a leaf spring and fitted with a main mobile contact which is attached to and detached from the main fixed contact. The arc contact unit and the auxiliary contact unit are arranged adjacent to each other. The main contact spring extends in a direction in which the arc contact unit and the auxiliary contact unit are arranged. Therefore, the main contact spring can be formed with a large length in the frame body and the sectional area can be enhanced without increasing a spring constant, thereby not requiring a braided wire.
