| Contd. -6- ELECTRICALLY OPERATED MAIN SWITCH AND JAW CLUTCH ACTUATOR. Operation of the push button switch on the dash excites in parallel the electromagnetic windings of the main switch and jaw clutch actuator A (figs. 59 & 60). The armature of the latter, when attracted, actuates the jaw clutch through a lever L, and a rod R, running through the hollow layshaft. A spring toggle mechanism working on the lever ensures that the jaw clutch is either fully engaged or fully disengaged. The teeth of the clutch are backed off on their non-driving faces, ensuring their automatic disengagement when the engine starts and the push button switch is released. The main switch on the front of the dash as shown with cover removed in fig. 60. The attraction of the electromagnet S on its armature M, closes the main motor circuit through copper contacts C. Carbon contacts B are provided to take the break. Contd. | ||
