# This test demonstrates the behavior of the `Switch_Greater_Than_equal` component.
#
# The test connects a sine wave signal (`sine.y`) as both the `switch_primary` and `input_primary`,
# and a constant signal (`constant1.y`) with value 0 as the `input_secondary`.
# Since Threshold = 0, the switch output behaves as:
#   - When sine.y ≥ 0 → output = sine.y  (passes through the sine wave)
#   - When sine.y < 0 → output = 0  
#
# Now During positive half-cycles of the sine wave, output follows the sine signal and 
# during negative half-cycles, output remains at 0.This creates a “half-wave rectified”
# waveform at `switch_.switch_position`.
