Abstract
A multiple contact switch having at least one elastically deformable contact spring that is deformed by means of projections from a plunger to initiate contact with normally-open electrical contacts within the switch. A normally-closed contact piece within the switch also confronts the normally-open contact. Upon deformation of the elastically deformable spring contact, contacts are made and interrupted by means of contacts affixed to the movable contact springs.
