Specification

What		Comments
Identifier	3P_TOGGLE_SWITCH

Notes

• With this sensor you can get the position of a DPDT (double-pole, double-throw) switch.
• A DPDT has 6 terminals, organised in 2 rows. This sensor only use one row of terminals. Connect the common terminal to GND and each of the other terminals to a GPIO.
• Hardware pull-ups are not required.
• Hardware debouncing are not required.
• When the GPIO level state changes the sensor reads the switch position and a callback is executed reporting the switch position.

Code

-- Attach the switch to GPIO26 and GPIO14
s = sensor.attach("3P_TOGGLE_SWITCH", 26, 14)
s:callback(
   function(data)
      print(data.pos)
   end
)
