[James Bond] Why do mundane items, like gym equipment, have a kill setting?

A number of times Bond is almost killed by something, like a back stretcher, simply by changing the setting to what is apparently "Kill".

Why is this even a thing?

Nowadays it's all safety labels and child-proof products, but back in the heady days of the Cold War death was an ever-present possibility.  Government mostly kept its nose out of business and focused on the larger picture of making sure that the nukes didn't fly. 

If you wanted to make a back stretching machine that could rip a man in half or a personal sauna that could broil an egg, no one was going to stop you. These were trivial concerns when nuclear apocalypse was one misstep away.
