I have seen that happen before as well. A new rubber plug or something a little more durable will solve your problem for sure. Good reminder that just because the rubber plug is still there, doesn't mean that it isn't damaged and causing a no-start or intermittent start condition.

 

Go to your desk drawer, cut the eraser off the end and try gluing that on as a temporary patch...until you find a more suitable, longer wearing replacement.

(I disconnected my switch and rewired it as a SPST kill switch. 'We don't need no stinking clutch interlock switch.')

 

I bolted a small machine screw through the hole. Easiest fast fix I could come up with.

I've had a couple of bad clutch switches in the past and just bypassed them so the vehicle would start in gear. But I never did that.

 

JB Weld a penny over the hole. Or a dime, if you're a big spender.

Or
Brake pedal/clutch pedal plastic stop plug part number 46584-5P010 or
Dorman Accelerator Pedal Stop Pad 74015 Most folks epoxy or JB Weld in a dime to press plunger on the stoplight switch or a dime if one is a big spender.
