Abstract
An electromagnetic relay having a manual actuator wherein at an edge of the relay's housing is an opening formed in the shape of a mounting slot in which a pivot lever is mounted with a hinge segment. In an idle state, an outer lever segment of the pivot lever is lowered in a cavity of a housing wall while an inner lever arm extends along a housing wall perpendicular thereto. When the pivot lever is actuated, the inner lever arm actuates a movable relay part, in particular a bolt, up to a first operating position. When the pivot lever is rotated further, the inner lever arm can be locked with the movable relay part.
Claims20
An electromagnetic relay, comprising:
- a housing having a first housing wall, a second housing wall and a mounting slot, wherein the second housing wall is connected to the first housing wall at a substantially right angle such that the mounting slot of the housing is formed at an intersecting edge between the first housing wall and the second housing wall;
- a movable relay part within the housing positioned proximate the first housing wall wherein the movable relay part may be moved in a substantially parallel fashion with respect to the first housing wall;
- and
- a movable pivot lever extending through the mounting slot of the housing such that a pivot axle of the pivot lever is substantially parallel to the intersecting edge, the pivot lever including an outer lever arm positioned substantially external to the housing such that the outer lever arm is substantially parallel to the first housing wall in an idle relay state, an inner lever arm positioned substantially within the housing in operational engagement with the movable relay state, and hinge segment formed between the outer lever arm and the inner lever arm and pivotably mounted in the mounting slot of the housing.
- a movable realy part within the housing positioned proximate the first housing wall;
- and
- a movable pivot lever extending through the mounting slot of the housing, the pivot lever including an outer lever arm postioned substantially external to the housing, an inner lever are postitioned substantially within the housing in operational engagement with the movable relay part, and a hinge segment formed between the outer lever arm and the inner lever arm and pivotably mounted in the mounting slot of the housing, wherein the hinge segment includes a flattened catch surface for engagement with a portion of the second housing wall at a catch position.

An electromagnetic relay, comprising:
- a housing having a first housing wall and a mounting slot;
- a movable relay part within the housing positioned proximate the first housing wall;
- and
- a movable pivot lever extending through the mounting slot of the housing, the pivot lever including an outer lever arm positioned substantially external to the housing, an inner lever arm positioned substantially within the housing in operational engagement with the movable relay part, and a hinge segment formed between the outer lever arm and the inner lever arm and pivotably mounted in the mounting slot of the housing, wherein an elastically deformable part having a convex-shaped edge biased against the hinge segment is formed as part of the housing and positioned adjacent the mounting slot, the part biased against the hinge segment which has a concave-shaped edge for cooperative engagement with the convex-shaped edge of the deformable part to enable a snap-mounting of the hinge segment in the mounting slot.
