Can you wire a 120v male connector to a double outlet and then to a switch and plug the entire unit into and existing outlet to provide power to run a router table?

Yes, you can wire a 120V male connector to a double outlet, which can then be connected to a switch. However, it is essential to ensure that the entire setup is properly rated for the load of the router table and adheres to local electrical codes. Additionally, using a switch in this manner may not be advisable for safety reasons, and it's recommended to consult a qualified electrician to ensure safe and compliant installation.
