Billion Power Button Faulty

[Giarc86]

I have a Billion 7401 VGP router. It works perfectly fine except for the on/off button. It very seldom makes connection. Sometimes it will make connection and stay on if you move the button around a bit, but then it will just switch off again when it feels like it.

Does anyone know anything about them or what I can do as it is a perfectly fine router, just the button is faulty? It's not under warranty anymore.

Thanks
