resistance is omitted. The (25)A* differs from the (25)A only in wiring connections.
DESCRIPTION:
The fuze has three firing circuits and is of type 2 construction. A screw in the head operates a switch which cuts out the short delay circuit leaving only the long delay under plunger B.
SAFETY SWITCHING:
Each plunger cuts off the opposite arming circuit when depressed.
REMARKS: The (25)A differs from the (25) in that the 200M resistor is reduced to 60M. Arming time is about one third. The 10,000-ohm
