Load is energized when switch is closed C1 charges until voltage across R1 drops below 0.8V、opening LM195 and deenergizing load，Long time delays can be obtained with small capacltor values since high resistance can be used.- Linear Applications,vol 2, National Semiconductor．Santa Clara, CA, 1976,AN-110,p 4.
