Abstract
In a battery-operated electric release device for fire-arms having an electronic switch 11 arranged in line between a first capacitor 8 and an electromagnet 9. The battery 3 is connected to the capacitor with no additional mechanically operated switch arranged therebetween. The electronic switch 11 is fired by discharge of a second capacitor 14 through a trigger controlled mechanical switch 15. The second capacitor 14 is provided with a voltage divider 12, 13 so that its charging time is greater than that of the first capacitor 8, whereby the fire arm cannot be prematurely discharged.
