ABSTRACT:
A liquid level switch assembly is provided which can be adjusted as to what liquid level will actuate the switch. A support bracket is mountable to the tank and a float arm is pivotally mounted to the support bracket inside the tank by way of a pivot axle. A magnet is mounted to the pivot axle such that the magnet rotates as the float arm pivots to follow the liquid level on the tank but such that the angular position of the poles of the magnet can be adjusted relative to the float arm when the float arm is retained as the magnet is rotated. A reed switch is mounted on the support bracket near the magnet such that when the float arm is in a predetermined range of angular position relative to the horizontal, the reed switch is actuated by the magnet.
