ABSTRACT:
In combination with a fluid reservoir in which a magnetically operable switch is assembled to be closed by magnetic force of a permanent magnet on a float such that a warning signal is issued when the float moves down to a lower warning position dependent on a minimum fluid level in the reservoir, a check mechanism includes a spring loaded vertical rod extending into the interior of the reservoir from the exterior and arranged to be engaged at its lower end with the float when the surface of fluid is maintained at a predetermined level. When the vertical rod is pushed downward, the float is forcibly moved down to the lower warning position to check malfunction of the switch.
