Abstract
A bi-directional multifunction switch which incorporates a single contact carrier having conductive contacts adapted to be moved in various directions as a result of rotary and push/pull actuation of an interconnected knob. Electrically conductive circuit paths formed in a substrate surface are contacted by protrusions on the conductive contacts to accomplish electrical switching functions. The contact carrier is moved via a shaft which securely retains the contact carrier along opposing axes and which moves as a result of turning, pushing or pulling the actuating knob.
