Part Number: DRV5033
I want to use DRV5033 as non-contact push-button, I also use the tool to calculate the shape ,thickness.materials, but it seem DRV5033 sensitivity is not good for push button.
The travel distance is about 1.5mm, ferrite, diameter is 2mm-3mm, 0.5mm-1.0mm thickness.
Can you give me some suggestion for push-button design with TI hall switch?
I would recommend looking at the DRV5012 for your design. This device is a low-power latch and it is sensitive only to magnetic field polarity. Since field magnitude is not as important, the magnet can be placed very close to the sensor to produce a compact design. Please see figure below for concept.

Thanks for your support.
In fact, the direction of the ferrite and hall switch look like this picture. can DRV5012 use this way? the travel distance only 1.5mm.
