<p>PURPOSE:To easily and surely changeover a changeover switch with a simple structure by abolishing the coventional driving rotating body by electrical driving. CONSTITUTION:This switch changeover mechanism is provided with a freely advanceable and retreatable operating lever 2, a freely turnable changeover arm 8 having a sliding projection 11 at its front end, a changeover plate 3 having a sliding guide hole 12 for sliding of this sliding projection 11 and moving in a direction perpendicular to the operating lever 2, a switch changeover lever 20 turning according to the movement of this changeover plate 3 and a changeover switch 4 moving in a direction reverse from the moving direction of the changeover plate 3 according to turning of this switch changeover leer 20. A V-shaped flyer spring 14 is put on between the changeover plate 3 and the changeover arm 8. This flyer spring 14 is so energized as to maintain the turning position in sliding contact with the other side edge of the changeover arm 8 when the operating lever 2 is next moved to advance.</p> |
