A robotic crash protection device is adapted to be interposed between a robot arm and a robotic tool for detecting a crash. The device includes a housing, a piston having a generally central bore movably mounted within the housing, an actuator for engaging the piston and moving the piston in response to a crash, and a switch disposed within the housing and generally aligned with the bore of the piston. The switch contacts are disposed such that in a default position the bore of the piston engages the contacts and maintains the contacts in one switch state, and in the event of a crash the piston moves and permits the contacts to assume the opposite switch state. A non-circular contact surface between the actuator and the piston ensures a consistent response to lateral forces applied in to the axial direction in any radial direction.
