OEM integrators in the United States and Canada specify roller micro switches for position sensing where plunger-style actuators would bind or wear quickly. This guide covers actuator geometry, force\/travel trade-offs, and documentation you should request before approving a series for production. This guide focuses on practical evaluation steps for U.S. and Canadian OEM buyers\u2014specifications, sample qualification, and documentation\u2014not generic marketing claims.
