Stainless Steel Vertical Float Switch Liquid Level Sensor 10W

Product Description:  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).  This sensor works with any voltage/current (AC or DC) within the maximum limits as specified below.  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) Vertical mount; install either at the top or bottom of the tank NO (normally open) or NC (normally closed), convertible simply reversing the float. Combinations see below:  Top mount, switch open when the tank is full Top mount, switch closed when the tank is full Bottom mount, switch open when the tank is empty Bottom mount, switch closed when the tank is empty  Specifi
