## Abstract

An electronic accessory for a firearm includes a housing including a right side, a left side, and an attachment mechanism for securing the electronic accessory to the firearm. The housing contains components of the electronic accessory. The components of the electronic accessory include an electronic component, a sensor sensing a magnetic field, and a circuit board coupled to the electronic component and the sensor. The circuit board controls the electronic component and suspends power to the electronic component when the sensor senses a magnetic field above a threshold strength. A first switch is disposed on the right side of the housing and a second switch is disposed on the left side of the housing. The switches are operable to control the electronic component via the circuit board. A power source provides power to at least one of the electronic component, the sensor, and the circuit board.

## Claims

### Claim 1

An electronic accessory for a firearm comprising:
a housing including a right side, a left side, and an attachment mechanism for securing the electronic accessory to the firearm, the housing containing components of the electronic accessory, the components of the electronic accessory comprising:
an electronic component;
a sensor sensing a magnetic field;
a circuit board coupled to the electronic component and the sensor, the circuit board controlling the electronic component and suspending power to the electronic component when the sensor senses a magnetic field above a threshold strength;
a first switch disposed on the right side of the housing, the first switch being operable to control the electronic component via the circuit board;
