What's a dead man switch?
gpt
A deadmans switch is a device used by people like suicide bombers. The switch usually has a spring loaded lever that has to be held down with force to stop the ignition of what ever device its connected to. If the person holding the switch lets go of that lever without dearming the device it will explode. The idea behind them is that you cannot harm the person holding the switch without causing an explosion. Think of it like a (absolutely terrifying) insurance policy.

In the context of Epstein the deadman switch would most likely be a video of some of his more important clients performing illegal activities or some sort of blackmail. These videos would be hidden somewhere. If anything where to happen to Epstein they would be released to the public ruining the clients reputation assuring mutual destruction.
