<p>PURPOSE:To release interruption, in a relay for establishing interrupted condition through a movable chip comprising two sections upon submersion by energizing one section of the movable chip by means of a spring and moving the movable chip forcibly through external force while maintaining the interrupted condition even after stoppage of power supply to a coil. CONSTITUTION:When sensor terminals 5a, 5b are conducted due to submersion, a second recess 10b is engaged with a protrusion 11 by the magnetic force induced by current flowing through coils 6a, 6b. Contacts 7a, 7b are opened to isolate the input terminals 3a, 3b of a relay electrically from the output terminals 4a, 4b. Second section 9b of a movable chip is continuously energized in the direction separating from the first section 9a by means of a spring 12. Consequently, second recess 10b is continuously engaged with a protrusion 11 even after breaking of conduction of the sensor terminals. Interrupted condition can be released by pushing the end E of the movable chip 9b from the outside of relay.</p> |
