Abstract
A relay, in particular for a starter for an internal combustion engine for use in a motor vehicle. The relay has a self-resilient contact bridge, which for a reversible change in shape effected by the contact pressure, in particular widening, is embodied in curved form.
Claims28
A relay, having a contact bridge,
- wherein the contact bridge (10) is self-resilient and is embodied in curved form for a reversible change in shape, occurring as a result of contact pressure,
- wherein the contact bridge (10) has a contact compression spring (31) and a contact plate (38) that is acted upon by the contact compression spring (31), and
- wherein the contact compression spring (31) and the contact plate (38) are embodied as adapted in shape to one another,
- wherein counterpart contacts (21, 22) are provided and arranged so that in a closed condition of the relay, the contact plate (38) directly contacts the counterpart contacts (21, 22),
- wherein the contact plate (38) has a contact plate opening (39) and the contact compression spring (31) has a contact compression spring opening (32),
- wherein the relay further has a switching pin (12),
- wherein the contact plate (38) and the contact compression spring (31) are jointly held on the switching pin (12) by the contact plate opening (39) and by the contact compression spring opening (32) correspondingly,
- wherein the contact compression spring (31) and the contact plate (38) lie over one another directly around the switching pin, when the contact plate (38) is spaced from the counterpart contact (21, 22).

The relay as recited in clam 1,
- wherein a contact bridge holder (11), effects the switching motion of the contact bridge (10) and engages a curved region of the contact bridge (10).
A relay, having a contact bridge,
- wherein the contact bridge (10) is self-resilient and is embodied in curved form for a reversible change in shape occurring as a result of contact pressure,
- wherein the contact bridge (10) has a contact compression spring (31) and a contact plate (38) that is acted upon by the contact compression spring (31),
- wherein the contact compression spring (31) and the contact plate (38) have at least one device (44) for rotary alignment and/or fixation relative to one another,
- wherein counterpart contacts (21, 22) are provided and arranged so that in a closed condition of the relay, the contact plate (38) directly contacts the counterpart contacts (21, 22),
- wherein the contact plate (38) has a contact plate opening (39) and the contact compression spring (31) has a contact compression spring opening (32),
- wherein the relay further has a switching pin (12).
- wherein the contact plate (38) and the contact compression spring (31) are jointly held on the switching pin (12) by the contact plate opening (39) and by the contact compression spring opening (32) correspondingly,
- wherein the contact pressure spring (31) and the contact plate (38) lie over one another directly around the switching pin, when the contact plate (38) is spaced from the counterpart contact (21, 22).
