ABSTRACT:
An electromagnetic relay including a holder capable of not only holding a light-emitting device but also causing a movable core to be moved by manual operation. In the electromagnetic relay, a coil is energized via coil terminals to magnetic and demagnetize a coil block and turn a movable core, thereby moving a movable contact part to open and close a contact. The electromagnetic relay includes a light-emitting device which emits light when the coil terminals are energized, and a holder including a holder body which holds the light-emitting device, an operating portion which moves the movable core by directly pressing the movable core through a depressing operation of the operating portion, and elastic arm portions which connect the holder body and the operating portion and are elastically deformed by the depressing operation of the operating portion.
