Abstract
An electromagnetic relay including at least one contact-set support in which a plurality of contact springs are fixed at the base end and, in pairs, form normally open and/or normally closed contacts, wherein at least one actuator acts on each active contact spring, the actuator being movably driven in the longitudinal direction thereof by a magnet system and having actuating surfaces for acting on the respective contact spring to be actuated, the actuating surfaces assigned to each of the active contact springs forming an angle with the direction of actuation of the actuator.
Claims13
A method for operating an electromagnetic relay comprising at least one contact-set support (1), a plurality of contact springs (15-20) having a base end fixed to the at least one contact-set support, said plurality of contact springs comprising a plurality of passive contact springs (18-20) and a plurality of active contact springs (15-17), pairs of which form normally open and/or normally closed contacts (22-24), wherein at least one actuator (7) acts on respective ones of the active contact springs (15-17), said actuator (7) being movably driven in the longitudinal direction thereof by a magnet system (2, 3, 4) and having actuating surfaces (26) for acting on the respective ones of the plurality of active contact springs (15-17) to be actuated, the actuation surfaces (26) of the actuator (7) assigned to each of the active contact springs form an angle (36) in direction of actuation of the actuator (7), the method comprising during the stroke of the actuator (7) causing an actuation plane on which the actuator (7) acts on the active contact springs (15-17) to change from one actuation plane (25) to another actuation plane (27), wherein the shifting of a point of force application during the stroke of the actuator and action on the plurality of active springs (15-17) to be actuated, is moved from an upper point of force application to a lower point of force application.
An electromagnetic relay comprising at least one contact-set support (1), a plurality of contact springs (15-20) having a base end fixed to the at least one contact-set support, said plurality of contact springs comprising a plurality of passive contact springs (18-20) and a plurality of active contact springs (15-17) pairs of which form normally open and normally closed contacts (22-24), wherein at least one actuator (7) acts on respective ones of the active contact springs (15-17), said actuator (7) being movably driven in the longitudinal direction thereof by a magnet system (2, 3, 4) and having actuating surfaces (26) for acting on the respective ones of the plurality of active contact springs (15-17) to be actuated, wherein the actuating surfaces (26) of the actuator (7) that are associated with the respective plurality of active contact springs (15-17) form an angle (36) with respect to the longitudinal direction of actuation of the actuator (7) and wherein the shifting of a point of force application during the stroke of the actuator and action on the plurality of active springs (15-17) to be actuated, is moved from an upper point of force application to a lower point of force application.
