| 844 Contd. (3) In an endurance test recently conducted on the sequence starter system on our crankshaft rig, this switch was operated 20,000 times without failure. We therefore recommend fitting one of these switches to an experimental chassis for standardization test. The switch we have been using could be fitted to either 19 or 20EX and the standard switch removed handed to us. H E West. | ||
