This mine has a visible knob on its top. The knob houses a spring-loaded anti-removal contact which is held open by a weight, such as a rock, when the mine is laid. The mine is about 6 1/2 inches long, 5 1/2 inches wide, and 2 1/2 inches high. It contains about 1 pound of explosive. A safety arming contact is also provided and is held open by a cord led through a hole in the top of the mine and tied to a nail in the side of the mine.
This mine is used as an initiating mine for large charges and also as a booby trap.
In addition to functioning like the electrical pressure mine, this mine also functions if the weight is lifted from the anti-removal contact. This action allows the spring-loaded contact to rise until the circuit is closed, detonating the mine.
