“PerkinElmer’s Mini-Triggered Spark Gaps are designed for high reliability switching up to 4 kV and 10 kA. Constructed of hermetically sealed ceramic-metal, filled with pressurized gas, they are typically used for activating electro-explosive devices such as exploding bridgewires, electronic safe and arm systems, and detonators.”

A ako se odnosi konkretno baš na PerkinElmer’s Mini-Triggered Spark Gap, tada bi se možda moglo (slobodnije) prevesti i sa inicijator, detonator, elektro-detonator ili sl, sve zavisi od konteksta.
