## Abstract

A multi-function dry fire training device to be inserted into the chamber of a firearm, which comprises an illuminator for emitting, upon receiving a command from a controller, a beam of visible or invisible illumination from the barrel of the firearm, the beam being parallel to its central axis; a controller for controlling the functionality of the device including illumination of the illuminator, in response to activation of the firearm trigger; an actuator, being electrically connected to the controller, for activating the controller whenever being struck by the firearm striker and a power source for providing DC power to the controller and illuminator.

## Claims

### Claim 1

A dry fire training device for emitting light through a barrel of a firearm, comprising:
an illuminator for emitting a beam of light from the barrel of the firearm;
a control circuit for supplying power to the illuminator to emit the beam of light; and
a power supply positioned between the control circuit and the illuminator for providing power to the illuminator and the control circuit,
wherein the control circuit is connected by two electric conductors to the illuminator, a first conductor connected to a first pole of the illuminator and the power supply, and a second conductor connected to a second pole of the illuminator, and
wherein the electric conductors do not include a casing of the device.

### Claim 2 (depends on 1)

The dry fire training device of claim 1, wherein the control circuit includes a capacitor.

### Claim 3 (depends on 1)

The dry fire training device of claim 1 wherein the control circuit includes an electrically rechargeable component.

### Claim 4 (depends on 1)

The dry fire training device of claim 1, wherein the first casing including an actuator for generating an electric indication in response to a mechanical activation of the firearm.
