Which of the following is a common type of detonator?

Remote detonators are commonly used in explosive applications due to their ability to initiate an explosion from a safe distance. They provide a means for controlled detonation, allowing operators to avoid potential danger while ensuring precise timing. Unlike traditional methods that may involve direct manual ignition, remote detonators can be triggered via radio, wire, or other remote means, enhancing safety and flexibility in various scenarios.

Fuses, while they are also used to initiate detonations, operate through combustion rather than a remote signal. Light bulbs and mechanical switches do not serve as detonators in the context of controlled explosive initiation. Understanding the operational advantages of remote detonators helps highlight why they are prevalent in the field of explosives and demolition.
