I had my Spider-man game for quite a time now and today I registered that two bumper switches were reversed by my previous owner (upper left and upper right) . When I changed them, everything went fine. But when I did a switch test the upper right one hardly registered and the upper left one had a contact all the time. I noticed, when I bend those switches a bit, it took effect on the registering.
I don't know much about bumpers, so I suppose this is a noob question.
How would you bend those switches, maybe there is a trick to it or I do have to do something entirely else.
I greatly appreciate all of your help.

Thanks LTG,

I am going to try that out tomorrow, with that point bender. I've got something like that in the house.
I never had any problems with my Spidy before. This is the first real issue with it.
Tomorrow I am going to post how everything went.
It is around 10-11 pm in Germany now . That was a really exhausting day.

And you should also be sure to wait a few seconds maybe a minute, before you service the game.
I ran into an issue with the board once. I turned the power off, grabbed into the cabinet and got a shock. I damaged one of those tiny new transitors, that day.
Since then I wait at least half a minute before servicing my games.

Now lets come back to our (solved) issue.
I have bend the switches with the point bender, everything went fine.
It wasn't that easy, but it was worth it (I had to remove them, each time I wanted to bend them).

Now my Spidy has some bumper action I've never seen before. It makes the game feel like a total new game.
Thanks LTG and TheBlackKnight
