A screen‐printed mechanical switch based on an electrode structure on stretchable polyurethane (PU)‐foam film, Platilon U 4021, combined with a piezoelectric actuator, Smart Material MFC M‐4010‐P1, is proposed. The minimum actuation voltage of the prepared component is 300 V. The measured resistance was 2 Ω while closed and >0.5 TΩ when open. The electrode structure endured on average of up to 15.5 M cycles with movement ≥100 times greater than the ≤1 µm required for actuation. The results suggest that the switch could be advantageous for various e‐textile applications.
