MA organisations most frequently encounter contact VOIEDs which can be broken down as:
• Pressure
• Pressure release
• Tension
• Tension release
3.3.1. PRESSURE This subcategory of contact VOIED functions when pressure is applied on the firing switch. There are many specific types, but the following two examples show mechanical and electrical firing switch variants.
ׁ NOTE. Chapter 3 provides further technical details on a number of other variants
The first example is a pressure-initiated VOIED incorporating a mechanical firing switch. This is an improvised type grenade fuze incorporating a cocked striker. This striker is held back by a wooden matchstick that is intended to snap when weight is applied. To increase the contact area a car bulb cover has been positioned around the switch.
