need replacement indicator switch

[JonathanT]

I think I need a new indicator switch because my main beam flickers with the dipped beam whilst driving. If I push very gently, I can reproduce the problem and if I pull very gently, it stops flickering.

Can anyone confirm if I need Vauxhall part: 9181010 ?
I'm guessing that the much cheaper aftermarket parts are just fine....?

Might have one in the garage, I changed all mine about 6 years ago for complete units with Alloy? They were working fine the car had only done about 17000 at that time.
