Claims

[Scope of utility model registration request]

A common contact member, a normally closed contact member and a normally open contact member facing each other across the common contact member, and a central portion supported by individual cards,
a normally closed movable contact piece and a normally open movable contact piece that open and close between the common contact member and the normally closed contact member and between the normally open contact member;
Both cards are biased in parallel, and a return spring that holds the normally closed movable contact piece in the closed state and the normally open movable contact piece in the open state is pressed, and the central part of this return spring is pressed. An electromagnet that switches the normally closed movable contact piece to an open state and the normally open movable contact piece to a closed state, and a pair of grounding protrusions that the movable contact piece comes into contact with at least in the position where the normally closed movable contact piece is opened. The electromagnetic relay is characterized in that the distance between the pair of grounding protrusions that the normally closed movable contact piece comes into contact with is set smaller than the distance between the common contact member and the normally open contact member. relay.
