A modular initiator assembly comprising a receptacle and connector combination adapted to shunt the electrical contacts of the initiator as a default condition and to only unshunt the electrical contacts coupled to the initiator when the receptacle and connector establish a fully seated connection.

A detonator to activate energetic materials in downhole well environments that can be transported and operated safely. The detonator comprises a switch coupled to a power source and the energetic materials. The power source may or may not be a part of the detonator. The switch creates a default closed switch between the power source and the energetic material. The switch can communicate with an actuator in response to engaging a gun assembly. The switch can create an open switch in response to communicating with the actuator. The switch forms a short circuit when configured to the default closed switch and forms an open circuit when configured to the open switch. The energetic material is activated in response to the mechanical switch forming an open switch and power is provided by the power source.
