Abstract
An electric fuze, especially for hand grenades, having a power source which is activatable by the effect of a force for supplying output power and a delay unit for delaying the ignition of a primer with respect to the time of activation of the power source. The delay unit has a variable time constant and includes an RC circuit formed of a plurality of series or parallel connected resistors and/or capacitors which are functionally connected with one another by electrical leads which leads are arranged to be open-circuited for the purpose of changing the delay time in a predetermined manner.
