GERMAN FUZES
(28) B2 AND (28) B6 – ELECTRICAL IMPACT FUZE
DATA:
Bombs Used in: H.E. bombs.
Color: Dark grey; yellow paint on shoulder.
Material: Aluminum.
Possible Actions: (a) Instantaneous. (b) 0.06 - 0.08 sec. delay.
Principal Markings:
El.A.Z. (28) B2.
El.A.Z. (28) (B)2.
El.A.Z. (28) B6.
Secondary Markings:
AA 1940 bmv 1940.
AA 1941 bmv 1941.
FC 1940 bmv 1942.
c 1940 Rh.S. 1940.

DESCRIPTION. Two firing circuits are employed in these fuzes, both charged through the B plunger. The impact switch closing the instantaneous firing circuit is an inertia bolt switch and operates only against resistance targets; i.e., upon deceleration of about 5,000 g.

Safety switching is accomplished through depression of the A plunger, which switches off both arming circuits. (See fig. 162.)

ARMING TIMES:

Level Flight
(150 v.)

Diving Flight
(240 v.)
Instantaneous: 1.8 - 3.2 sec. 1.4 - 2.2 sec.
Short delay:

REMARKS. 1. Type 2 construction. 2. These fuzes have also been recovered with the charging condenser connected to the A plunger. 3. An inherent delay of about 0.01 se-cond is present in the instantaneous circuit.
