Abstract: A zone valve control system for a flow valve comprising a direct current rotary electric motor connected to a valve shaft, an electronic control system comprising a microprocessor, an electric measuring device for signaling the presence of a predetermined electrical stall current, a rectifier and a regulator to convert and regulate external AC voltage to a desired DC power output; and an electrical storage system having a total storage capacity sufficient to power the DC electric motor to move the valve between the closed and opened positions; an external sensor for signaling when a certain condition exists in an external zone; the microprocessor controlling the flow and polarity of DC current to the motor; whereby the electronic control system controls movement of a valve operably connected to the output shaft to open or close a valve to maintain a desired predetermined condition in the external zone.

Abstract: A miniature rotary electric switch having push-in wire terminals comprises a housing which is about 1 inch in length, 1 inch in width and 0.2 inches in thickness and which includes a plurality of wire receiving openings. A plurality of Z-shaped stationary contacts are positioned inside the housing and a rotatable contactor is disposed inside the housing for selectively contacting the stationary contacts. Each stationary contact is positioned to overlie at least a portion of one of the wire receiving openings for locking engagement with a wire to be inserted therethrough. Each stationary contact includes a locking tongue, a spring finger and an intermediate arm, the intermediate arm linking the locking tongue to the spring finger. The locking tongue is connected to the intermediate arm at a first bend and the intermediate arm is connected to the spring finger at a second bend.
