horn faulty

[MikeBike]

Hello Guys.I have a FZS 600 1998-99.My bikes horn is a bit faulty. The horn itself works, but i need to try different ways of pressing the switch for it to actually works. I mean, if I need to give it a slight , rapid  touch for example to alert other drivers, it doesn´t work. Only after I try different pressing points and different amount of "force" on the switch  I manage to make it work.Do you experience this? What´s the issue?
ThanksMike
