CONTACT DEVICE Russian patent published in 2017 - IPC F42C1/00 F42C19/12 

FIELD: weapons and ammunition.

SUBSTANCE: device contains at least two, preferably more, sensitive elements, made in the form of microelectromechanical systems (hereinafter - MEMS-device), triggered by overload. One of the MEMS-devices is located in such a way, that the triggering is performed by the action of axial overload, exceeding the threshold level. The input of the mentioned MEMS-device is connected to the power input of the contact device, the output of the mentioned MEMS-device is connected to the input of the electronic time unit, providing the countdown of the longitudinal overload action and performing the target identification signal supply to the output of the contact device in case of exceeding the duration of the overload action, exceeding the threshold level of the certain time value. The rest MEMS-devices are electrically connected in series and arranged around the longitudinal axis of the contact device, preferably diametrically opposed, and arranged so, that its actuation is effected by centrifugal forces, when the contact device rotates about the longitudinal axis. The input of the first indicated MEMS-device circuit is connected to the output of the electronic time unit. The output of the latter in the indicated MEMS-device circuit is connected to the output of the contact device, at that the transmission of the signal from the electronic time unit output to the contact device output is provided upon the condition if all centrifugal action MEMS-devices are triggered.

EFFECT: increased sensitivity at contact destruct, increased resistance to small-size return action at the projectile trajectory, high level of security in the service handling.
