Clockwork indicating fuse.
An
indicating fuse is a power limiting device which cuts the flow of electricity when overloaded. It contains a spring loaded pin which pops out when the fuse
“blows”.
This fuse will trigger
the
detonator
(see ITA-128 &
ITA-129). Works with
moving hands of alarm clock.

Indicating fuse
lED.
Initiated by operation of indicating fuse plunger. Plunger pops out when the circuit it
is
inserted
into overheats or
shorts out.
The force
of the
moving plunger
can be used
to close a second circuit, firing a device.
This version is used only with 120 volts alternating current
(A.C.).
Extra fuses are
supplied with this
training model.

Indicating fuse
device
lED.
This
device is so designed that it remains safe until armed by the indicating fuse arming device. The plunger
in
the fuse, when shorted out, pops outward from the end or side of the fuse
and acts on a
microswitch, arming a second circuit in the
lED.
This circuit has its own method of initiation which
now comes
into play.

Barometric arming/Initiating Device.
First
barometer arms the device
by triggering an indicating fuse. At later change of air
pressure, second barometer
initiates a detonator. |
