Can I have (pointers to) more instructions as to how to solder the
switch?
What are solder pads?
The contact points are silver if this helps.

Solder pads = contact points. The fact they are still silver indicates they
are probably OK, so that's a good start.

I did manage to power on the mobile by connecting those points via a
wire


That's Good. You'll need a fine tipped soldering iron, preferably a
temperature controlled one but it's not essential. Use fine rosin cored
solder. Put the switch in place, and if possible get someone to hold it down
for you. When you are happy that the switch is located correctly, apply the
tip of the iron gently to one of the switch legs and solder pad. Quickly put
the solder onto the contact (not the iron!) and it should flow freely and
join the leg and the contact point. Repeat on each connection. Each one
should take a second of soldering time, any more and something is wrong-
either your iron is not hot enough, your technique is incorrect or the parts
to be soldered are tarnished/coated with something. If you keep the iron on
too long, the solder pad and possibly the switch will be destroyed and the
repair will be difficult to impossible.

While working on the phone, you must take antistatic precautions. Working on
an earthed metal kitchen sink will suffice if you don't have antistatic
wristbands etc.
