Switches – Improvised Types

In an electrical circuit a switch is a ma-made device (commercially manufactured, or improvised) that is capable of creating a break in the flow of electricity—and then restoring it. An improvised switch is a set of electrical contacts mounted on a strip of wood or plastic or in a small plastic container. One contact is fixed (cannot move) while the other contact can be moved. When moved in one direction it opens a gap, cutting power through the circuit at that point.

When moved the opposite way, contact is restored and power flows again. Improvised switches are crude and often unreliable. Each one is hand made, and quality control is lacking.

Securesearch manufactures a range of about 20 improvised switches, using the type of commonly available parts and pieces obtained from electrical supply stores, hardware stores, lumber yards, home renovation centers, plumbing supply stores and hobby shops. Many of the improvised switches are of the “boobytrap” type in an IED, that target the expected action of an unsuspecting victim. The mousetrap is one of the most commonly-adapted devices, converted into a boobytrap switch.

ELECTRONIC DELAYED ARMING, RADIO-CONTROLLED IED
Order Sku: ITA-102
Electronic delayed arming, radio-controlled IED. This device is a modified command detonation bomb model which can not be detonated at the exact instant the joystick control is operated. The joystick control simply starts an electronic automatic arming sequence. This is a safety feature to prevent (or at least attempt to thwart) electronic countermeasures jamming by a scanning transmitter moving up and down the radio frequency channels. Once the firing sequence has been started by the bomber, the bomb will detonate only after the electronic arming delay has set itself; the delay is variable and is set by us at the factory to the user’s request (typically 8-10 seconds to thwart a sweep by E.C.M. equipment). Transmitter is handheld, portable, with range variable from 1/4 mile to 1 mile. Receiver uses dual servos for redundancy, contains detonator and simulated dynamite or plastic explosive, LED, and whistle.

ALTIMETER SWITCH INITIATED IED
Order Sku: ITA-115
Altimeter switch initiated IED. Built around functioning aircraft altimeter on 2’ X 2’ display board, with stand. Uses small electric (120 volt) vacuum pump to exhaust air from altimeter; simulating a rise in altitude, as if installed in an aircraft which is ascending from ground level. Where available, we also attach to the board a set of working parts from the inside of an altimeter to illustrate their appearance and demonstrate their functioning.
