safety fuse

In each room there will be one lamp with its switch to turn it on or off as desired, and a safety fuse.

Besides luncheon baskets and materials to make lemonade, we had taken along axes, two crowbars, two lanterns, four pounds of blasting powder and three feet of safety fuse.

A safety fuse blew out, causing the flare and the explosion, and a piece of the soft lead-like metal had hit the red-haired lad in the eye.

Let us look at the safety fuse; why, there is none! it has been missed out.

If this cannot be felt, there must be some part or other disconnected, perhaps the safety fuse has given out, or the ends of the leads got adrift from the bracket.
