Original Logitech Replacement Ball for Logitech M570 Wireless Trackball

this is a Logitech Trackman it's the model in 570 the left mouse button is no longer working right and either triple clicks doesn't click and I recently found out that the switch in here has a part number on it and you can buy the individual switch I found the switches on eBay they were about a dollar each so I'm going to show today how to take this apart this is going to require a soldering to get that new switch in but it's relatively easy to take this apart the first thing you have to do is remove the rubber fee this one you don't have to remove since the screw is right next to the rubber foot but the rest of the rubber feet need to come off so you can get to the screws and there's a small Philips in here so you're going to need a small Phillips driver to get those screws out I won't show up removing all these screws but we'll come back after I have that port also the last screw requ
