Abstract
A telephone hook switch assembly has a housing which defines first and second cavities and a shaft rotatably mounted in the housing. A hook switch lever is mounted on the shaft and is rotatable therewith in the first housing cavity. A switch assembly having snap-action switches is positioned in the second housing cavity. The snap-action switches open and close in a predetermined sequence in response to rotation of the hook switch lever. The assembly provides superior isolation of the electrical contacts from environmental contaminants and is more rugged than conventional leaf spring and program card arrangements.
