Invasens has a number of
concepts for mercury tilt switch
replacement at the working prototype stage available for license or
funded development. These alternative mercury free solutions
are all low cost,
but high performance with volume production in mind. All
operation with highly predictable switch points.
The friction free technology results in switch point accuracy of better than 1 degree, typically 0.1 degree. Hysteresis of switch point is integral to the designs as is absense of contact bounce. For minimum production cost these designs are best realised in injection moulded plastic, although CNC production may be a viable option for low volume situations.
