williams space mission you guys helped me get going is working well still ,but sometimes on player one only the 100,000 point switch sticks on.i can manually open it on the back and it will stay off until the proper time ,or if i turn the machine off and on it will reset and stay off ,i cleaned the contacts already any suggestions

just saw thew other posts on a space mission scoring issues will look into the 100,000 switch better ,it may be worn a little too or maybe spring not strong enough anymore to release switch
