US Patent 10151181 Selectable switch to set a downhole tool

A perforating gun includes a carrier, an explosive charge positioned within the carrier, a detonator positioned within the carrier, and a switch positioned within the carrier. The detonator detonates the explosive charge when the detonator receives power. The switch actuates between at least a first position and a second position. The switch transmits power to the detonator when the switch is in the first position, and the switch transmits power to a pyrotechnic device when the switch is in the second position. The pyrotechnic device detonates or deflagrates when the pyrotechnic device receives power.
