A switch assembly for a valve actuator can include a bracket, a rotatable switch rotatably coupled to the bracket at an adjustable angle, a fixed switch fixedly mounted to the bracket, an arm rotatably coupled to the bracket, and an adjustable switch trigger coupled to the arm. The rotatable switch can be tripped by the valve actuator and a trip point of the rotatable switch can be calibrated by setting the adjustable angle. The fixed switch can be tripped by the switch trigger on the arm and a trip point of the fixed switch can be set by adjusting the switch trigger relative to the arm. The assembly can include a calibration fixture for calibrating the switch assembly to the valve actuator independently of the valve actuator.
