Abstract
Self-selecting switch devices, perforating gun systems including the devices, and methods of using the gun systems are provided herein. A self-selecting switch device includes a microcontroller, a logic circuit, and a first switch. The microcontroller is configured for direct operative connection to a shooting panel and to other self-selecting switch devices, wherein the microcontroller is programmed to detect a presence of other self-selecting switch devices that are operatively connected thereto. The first switch is operative to electrically connect a shooting panel to a detonator. The first switch is under operational control of the microcontroller. The logic circuit is in electrical communication with the microcontroller and the first switch. The logic circuit is configured to selectively direct electrical current to the microcontroller or to the first switch.
