“The Pressel Switch can be wired up for a Push or Pull Button activation. The ‘Pull’ switch is used in a normal Tripwire mode to block access or ingress routes and the ‘Push’ or ‘Stamp’ Pressel Switch is used in a Command initiated Role, with IEDs hidden in dead ground or behind obvious cover. When attacking forces drop into these dead ground areas ISIS fires or triggers the command switch and detonates the concealed IEDs.”
