Abstract
A multiple cantilever spring contact switch has contact members stacked both vertically and side-by-side. The contact members are gripped at one end between surfaces which impose a predetermined inclination of the contact members relative to a base. A pivotally mounted lever on the contact assembly actuates the contact members and can also serve as a member which is actuated by a telephone handset. No specific spring is provided for the lever, the lever being biased by the spring contact members.
