Abstract
The disclosure is directed at a method and system for a pull-cord sensor assembly that includes an activation portion including a magnet portion for generating a magnetic field; a sensor portion for sensing a level of the magnetic field level; a comparator for comparing the level of the magnetic field with a threshold value; and a pull cord integrated with the activation portion.
Claims20
A pull-cord sensor assembly comprising:
- an activation portion including a magnet configured to generate a magnetic field;
- a sensor configured to sense a level of the magnetic field of the magnet;
- a comparator connected to the sensor and configured to compare the sensed level of the magnetic field with a threshold value to determine if the sensed level meets the threshold value;
- and
- a pull cord operatively connected with the activation portion;
- wherein the pull cord can be pulled in any three-dimensional direction from where the pull cord is integrated with the activation portion
- wherein the activation portion further includes:
- a pull-cord coupler including:
- a tip portion;
- a rib portion;
- a ramp portion connecting the tip portion to the rib portion whereby a diameter of the trip portion is less than a diameter of the rib portion;
- and
- a ring portion connected to the rib portion;
- and
- a plate portion having a central portion, the central portion integrated with the pull-cord coupler.
