The purpose of this document is to give an update on how the limit switch will be mounted on the brake pedal mechanism
Our Limit Switch:
The limit switch that we are using is the Omron D2AW-AO53H Sealed Ultra Subminiature Basic Switch.
Here is what I could find about it info-wise:
Datasheet: https://components.omron.com/sites/default/files/datasheet_pdf/B130-E1.pdf
Failure Solutions: https://components.omron.com/sites/default/files/ds_related_pdf/B146-E1.pdf
Couldn’t find a CAD model of our specific switch, but found a similar one from the manufacturer which is only missing the lever.
Manufacturers:
Ahnaf’s (Inaccurate) version):
Limit Switch Housing Design:
Important Design Notes:
Needed slight adjustability (~1mm) to move the housing back and forth to position limit switch
Part is most likely going to be 3D Printed
Wanted a solution that uses fasteners as opposed to other solutions (such as hot glue)
The limit switch actuation point is important (how far does the pedal need to depress for the limit switch to trip)
Original Design Concept (From Matthew):
The hole size and look were exaggerated for my understanding
Current Design:
With my (inaccurate) limit switch model
To Do:
Unsure of where the limit switch actually trips and how that will affect the design
Try to place a more accurate model of the limit switch into the assembly to test the spacing
