How can we fix this lamp?

We got this lamp from a family member. It is the kind where you have to twist the little metal knob on top to turn it on and off. The knob is missing, so we are using small pliers to twist it right now. Is there an easy diy solution? Or can we buy this little part? And how do you put it on? Thanks!
