1. An initiator head comprising:
a housing extending in an axial direction;
a circuit board provided in an interior space of the housing, a thickness direction of the circuit board being substantially parallel with the axial direction;
a line-in terminal provided on a first side of the housing in the axial direction and accessible from an exterior of the housing, the line-in terminal being in electrical communication with the circuit board; and
a fuse displaced from the circuit board in the axial direction, the fuse being in electrical communication with the circuit board; wherein
the circuit board is configured to activate the fuse in response to a control signal received at the line-in terminal; and
an exterior shape of the housing is rotationally asymmetric with respect to the axial direction.
