Using a desoldering pump or solder wick, clear the existing solder so that the microswitches can be freely removed. Should you encounter resistance when removing the switch be sure that any residual solder has been removed so as not to damage the pads when the parts are withdrawn.
Once the old microswitches have been removed and the board is clean, the new switches can be dropped in place. I used Panasonic EVQP0D07K switches which appear to be a direct replacement. These are a 'snap in' component so the legs of the component secure themselves snugly through the board, allowing easy soldering.
