Abstract
THE SWITCH OPERATING MECHANISM INCLUDES AN OPERATING LEVER 33 FOR OPERATING THE SWICTH, AN ACTUATING SPRING 35 FOR CAUSING THE OPERATING LEVER SWING TO A FIRST SWING POSITION FOR HOLDING THE SWITCH IN A FIRST STATE OR A SECOND SWING POSITION FOR HOLDING THE SWITCH IN A SECOND STATE, A SELECT LEVER 35 FOR SELECTING THE SWING DIRECTION OF THE OPERATING LEVER, A HOLDING ARRAGEMENT, AND A REGULATING ARRANGEMANT.THE HOLDING ARRANGEMENT IS A GROUP CONSISTING OF A FIRST OUTER DETENT 40 FOR HOLDING THE OPERATING LEVER IN THE FIRST SWING THE POSITION, A SECOND OUTER DETENT 43 FOR HOLDING THE OPERATING LEVER IN THE SECOND SWING POSITION, AND FIRST AND SECOND INNER DETENTS 39 AND 42 FOR HOLDING THE OPERATING LEVER IN A NEUTRAL POSITION FOR HOLDING THE SWITCH IN A THIRD STATE. THE REGULATING ARRANGEMENT INCLUDES A MOVABLE REGULATING MEMBER 32 WHICH COMPRESSES THE ACTUATING SPRING TO STORE ENERGY IN THE SPRING WHEN THE OPERATING LEVER IS IN THE NEUTRAL POSITION, AND WHICH STRETCHES THE ACTUATING SPRING TO STORE ENERGY WHEN THE OPERATING LEVER IS IN THE FIRST OR SECOND SWING POSITION. THE MECHANISM IS COMPACT, SIMPLE IN CONSTRUCTION AND RELIABLE. ( FIGURE 1A ).
