ABSTRACT:
A multi-position apparatus for use with a system operated in at least three distinct positions. The apparatus comprises (i) a position-selection mechanism, (ii) a first link mechanism and a second link mechanism, each link mechanism being operably coupled with the position-selection mechanism, (iii) a first weight-actuated spring mechanism operably coupled with the first link mechanism, (iv) a second weight-actuated spring mechanism operably coupled with the second link mechanism, (vi) a first output-actuating member operably coupled with the first weight-actuated spring mechanism, the first output-actuating member being arranged to operably communicate with the system, and (vii) a second output-actuating member operably coupled with the second weight-actuated spring mechanism. In one example, the system may be an electrical transfer switch having two separate set of electrical contacts.
