I have a Ridgid OSS EB44242. The power switch went out and had to replace it. Wanted to note how it was done.
First, EB44242 model is the same as EB44241. The 2 specifies a different manufacturing location.

Before ordering a new switch you should check the existing switch to make sure it is bad. Unplug sander and remove bottom base. You could pop out the switch, but it is difficult to do. I did not want to break it in case it wasn’t the problem. So I removed the bottom base. I unplugged the switch from the wires.
Use a multimeter to check the ohms across the switch. Save the switch just in case.
The images of the switch below are of the original switch. Didn’t take pictures of the new switch before I installed it.
There is also a relay inside the unit.

I ordered the replacement switch from ereplacementparts.com. The original switch is not available so the new switch will have a different part number. Use the wiring diagram to match up the part number and part. It is easy to identify the part on the diagram. The only model they have is the EB44241. It is the same model, so order the switch for it. Less than $20 including shipping.

You’ll notice the new switch looks different than the original switch. The original switch has only two connections. The new switch has four connectors. That is ok. Use two vertical connectors that are on the same side.
The negative wire connects to the original switch with a smaller size terminal connector than the white wire.
You’ll have to replace the wire terminal connector on the black wire to connect it to the new switch. I cut off the existing one and saved it in case I had to reuse it. A generic solderless quick connect was used on the wire. A set of crimping pliers crimped the connector.

One item to note. Don’t turn the sander on when it is on its side. Doesn’t like that and will start to shake and smoke.
