Pressure plates are an extremely common VOIED switch. In MA they can be divided into high metal content and low metal content (see Chapter 3). Both operate under the same concept of two electrical contacts that are held in an open position. When pressure is applied, these contacts close and the circuit is completed, allowing electrical current to flow in the circuit causing the IED’s initiator / detonator(s) to function.
