Actuation Cycle

I reached the intersection perimeter. Target acquired: the heavy stainless-steel actuator recessed into the yellow signal box. Bracing against the concrete curb, I drove my right knuckle forward into the disc's center. Mechanical resistance yielded with a crisp four-millimeter travel. The internal switch engaged with an audible click. Instantly, an amber indicator illuminated alongside a steady acoustic pulse: eighty beats per minute, commanding the transit rhythm. Across the asphalt, the opposing digital display began its linear countdown. Relay verified.
