Abstract
An electromagnetically actuable device includes a base. A magnetic core is fixedly mounted to the base. An armature is movably mounted to the base proximate the magnetic core. A coil is fixedly mounted to the base and is selectively energized to draw the armature to the magnetic core. The armature and magnetic core have mating surfaces adapted to provide three contact areas in a triangular configuration to provide minimal magnetic air gap and a stable interface when the coil is energized.

An electromagnetically actuable device having a magnetic core proximate an armature and a coil selectively energized to draw the armature to the magnetic core, comprising:
- the armature and magnetic core each including legs having mating surfaces that provide three contact areas, where the mating surfaces contact one another between the corresponding legs of the armature and magnetic core, the three contact areas provided on the mating surfaces of the legs of the armature and magnetic core being in a triangular configuration to provide a stable interface when the coil is energized.
An electromagnetically actuable device comprising:
- a base;
- a magnetic core fixedly mounted to the base;
- an armature movably mounted to the base proximate the magnetic core;
- and
- a coil fixedly mounted to the base and being selectively energized to draw the armature to the magnetic core,
- the armature and magnetic core each including leas having mating surfaces that provide three contact areas, where the mating surfaces contact one another between the corresponding lees of the armature and the magnetic core, the three contact areas provided on the mating surfaces of the leas of the armature and magnetic core being in a triangular configuration to provide a stable interface when the coil is energized.
