The invention relates to a switching relay (1), particularly for a starting device for starting an internal combustion engine, having a contact device (5), a relay coil (2), an armature (3), and an actuating rod (4), wherein the actuating rod (4) is displaced by the armature (3) when current is appl
The invention relates to a switching relay (1), particularly for a starting device for starting an internal combustion engine, having a contact device (5), a relay coil (2), an armature (3), and an actuating rod (4), wherein the actuating rod (4) is displaced by the armature (3) when current is applied to the relay coil (2) and the contact device (5) is actuated by the actuating rod (4), and having a contact ripping device by means of which the armature (3) and the actuating rod (4) are coupled to each other. In order to simplify assembly and disassembly, the contact ripping device is implemented having a latching device in the armature (3).

1. A switching relay (1) having a contact device (5), a relay coil (2), an armature (3), an actuating rod (4) moved by the armature (3) when current is supplied to the relay coil (2), the contact device (5) being operated by the actuating rod (4), and having a contact breaking device by which the ar
1. A switching relay (1) having a contact device (5), a relay coil (2), an armature (3), an actuating rod (4) moved by the armature (3) when current is supplied to the relay coil (2), the contact device (5) being operated by the actuating rod (4), and having a contact breaking device by which the armature (3) and the actuating rod (4) are coupled to one another, with the relay coil (2) and the contact device (5) being formed as an assembly, wherein the armature is in the form of part of an unlatching apparatus for the contact breaking device, and the assembly of the relay coil (2) and the contact device (5) are formed such that they are pushed into the armature; wherein the unlatching apparatus comprises a shoulder (10) and an interengaging mating bearing (9); wherein the actuating rod (4) has at least one latching lug (9) as the mating bearing (9) and the armature (3) has a shoulder (10), with the shoulder (10) forming a stop face (12) for an end face (11) of a limb end of the latching lug (9); and wherein the stop face (12) of the shoulder (10) and the end face (11) of the latching lug (9) are each formed in an inclined manner with respect to the axial direction at a specific angle (α), for removing the actuating rod (4) from the armature (3). 2. The switching relay (1) as claimed in claim 1, wherein the actuating rod (4) is latched in the armature (3) with axial play in the current-free state of the relay coil (2). 3. The switching relay (1) as claimed in claim 1, wherein the actuating rod (4) and the armature (3) is unlatched with an unlatching force which is greater than a contact breaking force. 4. The switching relay (1) as claimed in claim 1, wherein the latching apparatus comprises a spacer bushing (8) with latching lugs (9). 5. The switching relay (1) as claimed in claim 4, wherein the latching apparatus, in particular the mating bearing (9), is produced at least partially from plastic. 6. The switching relay (1) as claimed in claim 4, wherein the latching apparatus, in particular the mating bearing (9), is produced at least partially from resilient metal material. 7. A starting apparatus for starting an internal combustion engine having a switching relay as claimed in claim 1. 8. A mounting method for a switching relay (1) having a contact device (5), a relay coil (2), an armature (3), an actuating rod (4), with the actuating rod (4) being moved by the armature (3) when current is supplied to the relay coil (2) and the contact device (5) being operated by the actuating rod (4), and having a contact breaking device by which the armature (3) and the actuating rod (4) are coupled to one another, with the relay coil (2) and the contact device (5) being formed as an assembly, wherein the assembly of the relay coil (2) and the contact device (5) are pushed into the armature and the actuating rod (4) is partially pushed into the armature (3) by way of its end which is opposite the contact device (5) and is latched into said armature such that it is unlatched; wherein the armature is in the form of part of an unlatching apparatus for the contact breaking device wherein the unlatching apparatus comprises a shoulder (10) and an interengaging mating bearing (9); wherein the actuating rod (4) has at least one latching lug (9) as the mating bearing (9) and the armature (3) has a shoulder (10), with the shoulder (10) forming a stop face (12) for an end face (11) of a limb end of the latching lug (9); and wherein the stop face (12) of the shoulder (10) and the end face (11) of the latching lug (9) are each formed in an inclined manner with respect to the axial direction at a specific angle (α), for removing the actuating rod (4) from the armature (3). 9. The mounting method as claimed in claim 8, wherein the switching relay is part of a starting apparatus for starting an internal combustion engine. 10. A removal method for a switching relay (1) having a contact device (5), a relay coil (2), an armature (3), an actuating rod (4) moved by the armature (3) when current is supplied to the relay coil (2) and the contact device (5) being operated by the actuating rod (4), and having a contact breaking device by which the armature (3) and the actuating rod (4) are coupled to one another, with the relay coil (2) and the contact device (5) being formed as an assembly, wherein the actuating rod (4) is withdrawn from the armature (3) in the direction of the contact device (5), with said actuating rod being unlatched with an unlatching force, which exceeds a contact breaking force, for unlatching the armature (3) from the relay coil (2) and the contact device (5) assembly; wherein the armature is in the form of part of an unlatching apparatus for the contact breaking device wherein the unlatching apparatus comprises a shoulder (10) and an interengaging mating bearing (9); wherein the actuating rod (4) has at least one latching lug (9) as the mating bearing (9) and the armature (3) has a shoulder (10), with the shoulder (10) forming a stop face (12) for an end face (11) of a limb end of the latching lug (9); and wherein the stop face (12) of the shoulder (10) and the end face (11) of the latching lug (9) are each formed in an inclined manner with respect to the axial direction at a specific angle (α), for removing the actuating rod (4) from the armature (3). 11. The removal method as claimed in claim 10, wherein the switching relay is part of a starting apparatus for starting an internal combustion engine.
