# This test demonstrates the behavior of the `Switch_not_equal` component.
#
# The component switches between two constant inputs (`a` and `b`) based on whether
# the control signal (`step.y`) is not equal to the specified threshold.
# Here for t < 5: step.y = 10.00001 (within tolerance → considered equal) → output = b.y = 2
# and For t ≥ 5: step.y = 10.00011 (not equal beyond tolerance) → output = a.y = 1
