ELPA Foot Switch for Nursing Care, Outlet Extension Cord, 2m This allows you to switch the power on and off with your foot, making it very convenient as you don't need to use your hands. I think it can be used for childcare, nursing care, and work. I am selling it because I no longer need it. I have cleaned it, so you can use it right away. There are two in the set. Operation has been confirmed.
