This is an after-market switch made by the Sparx Corporation and is almost identical to the original Lucas switch. This switch is for the right side with the starter button. The only difference between the stock switch and this new switch is thread on the screws that mount the master cylinder to this switch. The stock switch took four 3/16 x 32 screws and this new switch takes four 10 x 32 screws.
We also stock this switch without the starter button. This switch was used on Triumphs not Commandos, but could be used on a MK3 where the starter has been removed. The current price for this switch (part # 06-5929/A) is $135.00,
