German Tellermine Zunder 42

Here are a couple of Tellermine 42 fuses, T.Mi.Z.42. The load required to actuate the fuze in the mine varies between 570 and 580 lb. if app-lied to the cover plate above the fuze. With the load applied near the outer edge of the main cover plate, the lever effect reduces the required load which may be as low as one-half of the amount.

With the fuze removed from the mine, so that the resistance of the spring under the cover plate is excluded and only the shearing pin has to be severed, the load required is 495 lb.
