Abstract
A safety apparatus for personnel on an oil drilling rig includes a cylindrical quick disconnect switch having a receptacle and a plunger. The receptacle has an open circuit pair of electrical wires. The plunger is configured to attach to a derrick man. The plunger and the receptacle are configured to mate when the plunger is inserted into the receptacle and to remain frictionally mated until pulled apart. The mating results in closing the circuit between the pair of electrical wires.
