7940/7960 Off-hook switch repair - what ist the best way to fix this

There is a problem with the off-hook switch on 7940/7960 phones. After some time the switch does not work. When you pick up the handset nothing happens.

What is the best way to fix this?

1: Clean the switch circuit board with alcohol?

2: Replace the switch circuit board?

3: Replace the rubber part of the switch?

 

Is it possible to replace the switch with another kind of switch?

 

Any other suggestions?
 
Any help would be appriciated.
