Your satisfaction is guranteed or your money back! (Item may be returned within 30 days upon delivery for a full refund of the closing bid.  Shipping and handling is not refundable.)

Note: A small mechanical switch (aka. reed switch) sealed in the stationary part of the sensor is activated by a small magnet in the moving part (the float).  Therefore this sensor works with any voltage/current (AC or DC) within the maximum limits specified above.  All voltage/current/power ratings are for resistive loads.  However, one should always try to reduce the voltage and current applied on the sensor to a level as low as possible in order to extend the life of the sensor.  (For example, the Electrical Life is 5,000,000 cycles when the load is 5V, 10mA; 100,000 cycles when the load is 24V, 250mA)
