GERMAN FUZES

(25) C AND (25) D – ELECTRICAL IMPACT FUZE

DATA:

Bombs Used in: H.E. bombs as for (25) B.

Color: Dark grey.

Material: Aluminum in (25) C. Aluminum, sheet steel and plastic in (25) D.

Principal Markings: El.A.Z. (25) C; El.A.Z. (25) D.

Secondary Markings:

BL 42 on (25) C.
dtf f 15e on (25) D.

DESCRIPTION. The fuze is of type 2 construction and has four firing circuits, three of which are under plunger B in a parallel-series arrangement. A screw in the fuze head operates a switch which cuts out one of the short delay circuits leaving one short delay and the long delay under plunger B. Switch in position I - ON; position II - OFF.

SAFETY SWITCHING. The depression of either plunger switches off the opposite firing circuits. (See fig. 142.)

POSSIBLE ACTIONS:

	Switch Settings I		Switch Settings II
1.	Instantaneous.	1.	Instantaneous.
2.	Short delay (under 1 sec.).	2.	Short delay (under 1 sec.).
3.	Short delay (under 1 sec.).	3.	Cut out.
4.	8.5-sec. delay.	4.	8.5-sec. delay.

REMAKRS. The (25) D resembles the (25) tp in material and construction, but is opera-tionelly identical to the (25) C. In one recovered (25) D the setting screw by a metal plug. The long delay of the (25) D is reportedly 12.3 seconds.
