ABSTRACT:
A miniature switch has superior ability to switch small signals with high efficiency. A capsule encloses the switching contacts, the moving contact being provided with a magnetically permeable armature. A pair of magnetic pole pieces extend into the capsule and form an air gap closely adjacent the armature. When a magnetic field is applied across the air gap between the pole pieces, the armature is actuated and initiates the switching action.
