If the shaft that pulls in/out is still there but missing the button you don't need to replace the switch. On the top rear of the switch there is a button, you push the button and pull out on the shaft and it will pull out of the switch. To replace it you simply place the shaft back into the hole and push in, you will hear a click and it will latch into the switch. You can usually reach up under the dash and get to the rear of the switch to get to the button. If not the trim panel with the switch will be removable with some screws and the switch and panel comes out.
The problem is getting the knob assembly to match yours. That part is supposed to be reused from the old switch so replacement switches don't come with them. You can get replacement switches with them but they are usually expensive. The last image is the piece you need to replace. The point on the end is the latch pin that the button releases. Yo can get somewhat generic ones in many places online.
This is the same style switch as yours has and how the shaft is removed. If you have the replacement handy you don't need to disconnect the wiring or battery because you would just slide the broken one out and push the new one in.
