ABSTRACT:
A novel construction for a flashlight including a multifunctional rotary switching device is provided. The body of the switch includes an array of magnetic field effect sensors arranged on a base switch component such as a printed circuit board switching substrate. Each of the sensors is connected via circuit traces with a central logic chip also mounted on the circuit board. At least one magnet is installed into a rotatable actuator in proximity to the surface of the sensors whereby the magnetic field generated by the magnet causes the corresponding sensors to switch to an open position when at least one magnet is in their proximity. In this position, the logic chip can detect which of the sensors are open and execute a set of pre-programmed instructions corresponding to the sequence of open sensors.
