Installing a wireless remote switch for a ceiling fan in an existing single gang box

I installed a ceiling fan that has a wireless remote switch to control the light and fan speeds. It can be mounted in the wall in an existing single gang box. However the power to the fan must now be permanently on. To do this I am assuming that I just need to use a wire nut to connect the two black wires that go into the existing switch. I.e., remove the existing switch, connect the two wires going in to the switch, and then mount the remote switch in the existing gang box. Is that correct?
