Abstract
In a compact electromagnetic miniature relay comprising a contact spring (12) which is firmly clamped at one end, and which bears double contacts (9, 10) arranged on each side, and with the connecting line thereof extending vertically in relation to the longitudinal axis of the contact spring, and which are capable of being moved by an actuator (6) arranged on the armature (5), from stationary break contacts (7) to stationary make contacts (8), with said contact spring (12) being divided by a longitudinal slot (16) partly into two parallel spring legs (19, 20) pretensioned against the break contacts (7), and in which the actuator (6) engages between the clamping point (13) and the free end (11) of the contact spring, the actuator (6), according to the invention, is designed to have at least the same width as the contact spring (12) at the actuating point (17), with the longitudinal slot (16) beginning at a small spacing from the actuating point (17) and extending up to the end (11) of the contact spring (12), thus forming two spring legs (19, 20) which are capable of being moved independently of one another and which bear the pairs of switching contacts (9, 10), and within the area…
