НХ-ПЧ

The НХ-ПЧ electric igniter belongs to electric igniters with a nichrome resistance bridgewire. It consists of a bridgewire soldered to the ends of two insulated wires and a drop of igniting composition (TNRS) applied to the bridgewire and covered with a waterproofing layer. To protect against mechanical damage, the bridgewire with the drop is housed in a plastic sleeve. It is used in fuzes and firing devices.
