Electric detonators, electric matches and electric squibs contain a fine diameter wire filament (usually platinum) smaller than a human hair and coated with a layer of “match” material.

The bridgewire is crimped or welded across two copper or brass conductors, to which are attached two insulated copper “legwires”.

In contact with the match material is a “flash” charge that produces an intense burst of heat and flame when the bridgewire is energized from a power source. The flash detonates the sensitive high explosive in contact with it.

Our bridgewire inert products are technically accurate and x-ray correct. We use them in any simulated electric detonators requiring technical accuracy on x-ray –and to show proper electrical resistance on a blasting galvanometer.
