Description
This fuze is an instantaneous, mechanical, pressure type, with a spring-loaded lever electric contact. It consists of a spring-loaded brass plunger contained in a brass housing fixed to a metal base with the electric contact poles. The contact-rod end of the plunger projects at right angles through a slot in the housing. A spring-clip type of contact is fixed to the base of the fuze, outside the plunger housing. This fuze may or may not be contained in a wooden box with the lead wires running out and connected to a battery and electric detonator. A clock time device may be inserted in the circuit.
This fuze was most often employed in mining sections of railroad tracks, the head of the plunger being flush or nearly flush with the underside of the rail or tie.
Functioning
With the safety pins removed, pressure on the plunger head depresses the plunger until its attached contact rod slides into the spring-clip contact and closes the circuit.
