ABSTRACT:
A position detector for a check valve, including a bracket with a support arm, adjustable securing members adapted to rigidly secure the bracket to a check valve arm, a tilt switch, a connector, a circuit status indicator, a wire connector for both the tilt switch and the circuit status indicator, and a first plug. The connector adjustably connects the tilt switch to the bracket support arm in a selected one of a plurality of secure positions pivoted around an axis fixed to the bracket support arm, the axis being oriented generally horizontally when the securing members secure the bracket to the check valve arm. The first plug is selectively securable to the wire connector whereby a first circuit with the tilt switch and the circuit status indicator is formed when the tilt switch is in a selected position.
