To provide a relay, in particular for 42-volt automotive electrical systems, comprising a housing (10), two contact elements (60, 62) passing through the housing (10) and projecting beyond it, a magnetic coil (16) disposed in the housing and an armature (22) which is mounted pivotably in the housing (10), can be moved by means of the magnetic coil (16) and by means of which a contact bridge (100) can be moved between a contact position, electrically connecting the contact elements (60, 62), and an interruption position, which relay operates reliably at voltages higher than 12 volts, it is proposed that an elastic spring element (110) is movable between two elastic spring states by means of the armature (22) and that the elastic spring element (110) in one elastic spring state keeps the contact bridge (100) in the contact position and in the other elastic spring state keeps it in the interruption position.
A relay, in particular for 42-volt automotive electrical systems, comprising a housing (10), two contact elements (60, 62) passing through the housing (10) and projecting beyond it, a magnetic coil (16) disposed in the housing and an armature (22) which is mounted pivotably in the housing (10), can be moved by means of the magnetic coil (16) and by means of which a contact bridge (100) can be moved between a contact position, electrically connecting the contact elements (60, 62), and an interruption position, characterized in that an elastic spring element (110) is movable between two elastic spring states by means of the armature (22) and in that the elastic spring element (110) in one elastic spring state keeps the contact bridge (100) in the contact position and in the other elastic spring state keeps it in the interruption position.
The relay according to one of the preceding claims, characterized in that the elastic spring states are in the same way stable form states of the elastic spring element (110) which are separated from each other by means of an unstable intermediate state.
The relay according to one of the preceding claims, characterized in that the elastic spring element (110) is formed as a leaf spring element and the bending states are formed by bending states of the leaf spring element (110).
The relay according to one of the preceding claims, characterized in that, in the starting position of the armature (22), the elastic spring element (110) keeps the contact bridge (100) in the interruption position and, in the attracted position of the armature (22), the elastic spring element (110) keeps the contact bridge (100) in the contact position.
The relay according to one of preceding claims, characterized in that the elastic spring element (110) in a first bending state is bent away from the contact elements (60, 62).
The relay according to one of the preceding claims, characterized in that the elastic spring element (110) is mounted in the housing (10) by means of the armature (22).
The relay according to one of the preceding claims, characterized in that the elastic sring element (110) has at least one spring leg (116, 118), which is clamped between two abutments (112, 124, 126).
The relay according to one of the preceding claims, characterized in that the elastic spring element (110) has two spring legs (116, 118) which are spaced apart and extend from a contact bridge holder (112) to an abutment (124, 126).
The relay according to one of the preceding claims, characterized in that the elastic spring element (110) carries the contact bridge (100).
