A glass encapsulated, hermetically sealed, reed switch is embedded within the sensor body. A pennaruutt maguet in the sensors float creates a magnetic field which sur- '�- li rd Smid, rounds the reed switch holding the switch closed. When the magnetic held is removed by moving the float, the reed switch is actuated, thereby changing state Phis con- dition opus a closed switch. This change in state is then signaled to the control panel. 600121 'IVINECNOHIANH ,IIV,I TTOT999916 XVd 6Z:£T 90OZ/80/TT
