Abstract
An electromagnetic relay with at least one moveable contact spring, having an assigned normally-open contact, wherein the moveable contact spring is connected electrically-conductively to a first electrical terminal and the normally-open contact is connected electrically-conductively to a further electrical terminal, having a moveably mounted actuating element to move the moveable contact spring as a function of the current flowing through the relay in contact with the normally-open contact. The contact spring is equipped with two abutment surfaces, which are spatially separated from one another, and that the actuating element is equipped with two actuating surfaces, which are brought into active connection with the two abutment surfaces in order to move the contact spring.

An electromagnetic relay with at least one moveable contact spring, having an assigned normally-open contact, wherein the moveable contact spring is connected electrically-conductively to a first electrical terminal and the normally-open contact is connected electrically-conductively to a further electrical terminal, having a moveably mounted actuating element to move the moveable contact spring as a function of the current flowing through the relay in contact with the normally-open contact, wherein the contact spring has first and second sides with a central longitudinal axis extending along the length of the contact spring, intermediate the first and second sides, with the first and second sides being spaced transversely from the central longitudinal axis, the contact spring and is equipped with first and second abutment surfaces, the first abutment surface being positioned adjacent to the first side and the second abutment surface being positioned adjacent to the second side, and on opposite sides of the central longitudinal axis of the contact spring, and the actuating element is equipped with two actuating members, which are provided to seat against respective abutment surfaces in order to move the contact spring, wherein the two abutment surfaces are in relation to a contact region of the contact spring, disposed on opposing sides of the contact spring, and each abutment surface is provided on a sprung arm, which are connected to a base body of the moveable contact spring, the sprung arms extend laterally out from the base body from a region beneath the contact region and are carried upwards into the region of the contact region and are disposed at the side of the contact region, preferably with equal lateral spacing from the contact region, and preferably end at an identical height with the abutment surfaces for the actuating element.
An electromagnetic relay with at least one moveable contact spring, having an assigned normally-open contact, wherein the moveable contact spring is connected electrically-conductively to a first electrical terminal and the normally-open contact is connected electrically-conductively to a further electrical terminal, having a moveably mounted actuating element to move the moveable contact spring as a function of the current flowing through the relay in contact with the normally-open contact, wherein the contact spring has first and second sides with a central longitudinal axis extending along the length of the contact spring, intermediate the first and second sides, with the first and second sides being spaced transversely from the central longitudinal axis, the contact spring and is equipped with first and second abutment surfaces, the first abutment surface being positioned adjacent to the first side and the second abutment surface being positioned adjacent to the second side, and on opposite sides of the central longitudinal axis of the contact spring, and the actuating element is equipped with two actuating members, which are provided to seat against respective abutment surfaces in order to move the contact spring, wherein a third sprung arm is provided on the contact spring, wherein the third sprung arm is disposed above the actuating element and restricts the movement of the actuating element in an upward direction.
An electromagnetic relay with at least one moveable contact spring, having an assigned normally-open contact, wherein the moveable contact spring is connected electrically-conductively to a first electrical terminal and the normally-open contact is connected electrically-conductively to a further electrical terminal, having a moveably mounted actuating element to move the moveable contact spring as a function of the current flowing through the relay in contact with the normally-open contact, wherein the contact spring has first and second sides with a central longitudinal axis extending along the length of the contact spring, intermediate the first and second sides, with the first and second sides being spaced transversely from the central longitudinal axis, the contact spring and is equipped with first and second abutment surfaces, the first abutment surface being positioned adjacent to the first side and the second abutment surface being positioned adjacent to the second side, and on opposite sides of the central longitudinal axis of the contact spring, and the actuating element is equipped with two actuating members, which are provided to seat against respective abutment surfaces in order to move the contact spring, wherein the contact spring is equipped with a further abutment surface, wherein a third actuating surface of the actuating element is assigned to the further abutment surface, and wherein the actuating element draws the contact spring away from the normally-open contact as a result of the seating of the third actuating surface against the further abutment surface.
An electromagnetic relay with at least one moveable contact spring, having an assigned normally-open contact, wherein the moveable contact spring is connected electrically-conductively to a first electrical terminal and the normally-open contact is connected electrically-conductively to a further electrical terminal, having a moveably mounted actuating element to move the moveable contact spring as a function of the current flowing through the relay in contact with the normally-open contact, wherein the contact spring has first and second sides with a central longitudinal axis extending along the length of the contact spring, intermediate the first and second sides, with the first and second sides being spaced transversely from the central longitudinal axis, the contact spring and is equipped with first and second abutment surfaces, the first abutment surface being positioned adjacent to the first side and the second abutment surface being positioned adjacent to the second side, and on opposite sides of the central longitudinal axis of the contact spring, and the actuating element is equipped with two actuating members, which are provided to seat against respective abutment surfaces in order to move the contact spring, wherein a second moveable contact spring, which is of identical design to the first contact spring and disposed adjacent to the first contact spring, is provided, wherein the actuating element is designed to actuate the second moveable contact spring.
