A fuze is a device used to initiate an explosive charge, ensuring that it detonates at the right moment. Fuzes can be mechanical or electronic, and they are designed to respond to specific conditions, such as time, impact, or proximity. They play a crucial role in military applications, as well as in fireworks and demolition. There are various types of fuzes, including time fuzes, which activate after a set period, and proximity fuzes, which detonate when they come close to a target. Understanding how fuzes work is essential for safe handling and effective use in various applications.
