Abstract
A method for firing a detonator in a chain of switch assemblies includes a step of lowering the chain of switch assemblies into a wellbore; a step of powering-up a switch assembly of the chain of switch assemblies; a step of independently entering through a set of states during which the switch assembly interacts with a downstream switch assembly and determines a status of one or more elements associated with the switch assembly; and a step of firing a detonator electrically connected to the switch assembly or entering a sleeping state.
