MECHANICAL P.S.E. (Used with Mines Type LMB and Type LMA) (Figure 304)

This device consists of a spring-loaded firing pin which is held by two lock balls, when the tail door or mechanism plate to which it is attached is in its normal position, i.e., mine completely assembled. If an attempt is made to remove the tail door or mechanism plate, movement of a spring-loaded spindle allows the lock balls to move into a recess, releasing the spring-loaded firing pin to impinge on a special P.S.E. detonator, firing a two-pound charge to destroy the mine unit.

The device is armed prior to launching by removal of a safety pin which leaves the firing pin restrained only by the lock balls. The safety pin is removed from the mine case through a plug which is located 90° from the top center line on the flange.
