ABSTRACT:
An air-operated switching device includes first and second spaced supports on which an armature is mounted. The armature includes a resilient blade fixedly mounted at a first end on the first support and for sliding movement with respect to the second support. A resilient contact finger extends from the slidably supported end of the armature and includes a free end having a contact thereon. A fixed contact is positioned in alignment with the contact of the finger. An air-operated actuator applies pressure to the blade causing it to flex with the one end of the blade moving slidably over the second support, thereby causing the finger contact to be moved into engagement with the fixed contact with a wiping motion.
