ABSTRACT:
A detector plate for an overload clutch, the detector plate having at its peripheral edge a flat metal spiral retaining ring for providing improved detection by an adjacent proximity switch device. The spiral retaining ring provides an appropriate metal motion detection surface, for the customary plastic detector plate, any movement of which can be detected by the proximity switch. As an alternate embodiment, a metal surface coating can be formed onto the plastic detector plate to permit proximity switch detection of any movement of the detector plate.
