HALL SWITCH MODULE
 
- the module is suitable to switch any kind of small electric device (with a common positive leg)
- area of usage: controlling lights inside wagons, locomotives, houses or everywhere you want to hide the switch
- integrated Hall sensor
- on-board LED indication
- do not need to install a visible switch, because the on/off function is controlled by a magnet (not included)
- max. output current: 500 mA
- recommended power supply: 8-15V DC
- dimensions: 26 x 19 mm (1 x 0.75 inch)
- stand-by consumption: 9 mA
 
Function:
 
On startup, the output is off (output = HIGH). The LED flashes for 150 ms (milliseconds) in 2500 ms intervals to save energy in case of battery powering. 
Put the magnet close to the Hall sensor, the LED will light continuously showing the magnet has been detected. Hold the magnet for 2 seconds to switch on the output.
To switch off the output, repeat the same way as above: hold the magnet close to the Hall sensor for 2 seconds.
The maximal output current is 500 mA. In case you need to control a device with high consumption, use a relay with a protective 1N4007 diode (installed on a coil of a relay) or use a relay card.
