Flexible Plate Switch by the Jolly Roger
This flexible plate switch is used for initiating emplaced mines and
explosives.
/> Material Required:
—————–
Two flexible metal sheets
one
approximately 10 in. (25 cm) square
one approximately 10 in. x 8 in. (20 cm)
Piece of
wood 10 in. square x 1 in. thick
Four soft wood blocks 1 in. x 1 in. x 1/4 in.
Eight
flat head nails, 1 in. long
Connecting wires
Adhesive tape
Procedure:
———
1) Nail 10 in. by 8 in. metal sheet to 10 in. square piece of wood so that
1 in. of wood shows on each side of the metal. Leave one of the nails
sticking up
about 1/4 in.
2) Strip insulation from the end of one connecting wire. Wrap this end
around the nail and drive the nail all the way in.
3) Place the four wood blocks on the
corners of the wood base.
4) Place the 10 in. square flexible metal sheet so that it rests on
the
blocks in line with the wood base.
5) Drive four nails through the metal sheet and
the blocks (1 per block)
to fasten the sheet to the wood base. A second connecting wire is
atached
to one of the nails as in step #2.
6) Wrap the adhesive tape around the edges
of the plate and wood base.
This will assure that no dirt or other foreign matter will get
between the
plates and prevent the switch from operating.
How to use:
———-
The switch is placed in a hole in the path of expected traffic and covered
with a thin layer of dirt or other camouflaging material. The mine or
other explosive
device connected to the switch can be buried with the
switch or emplaced elsewhere as
desired.
When a vehicle passes over the switch, the two metal plates make contact
/> closing the firing circuit.
