ABSTRACT:
The present invention provides a spring integrally formed in a face plate of a housing for use with printed circuit board mounted operators having a central portion and J-shaped extensions. Stresses incurred when the central portion of the spring is pressed are distributed along the length of the extensions thus reducing maximum stress concentration in the spring. Additionally, material surrounding the spring is only minimally deflected when a spring is deflected, adjacent operators are not inadvertently actuated.
