the push button is suppose to have to be held for 10sec to turn the current controlled switch.  but you can just click it twice to get the circuit started. After it starts it will continue to run. the SPDT switch is to reset the push button timer circuit and to turn the timer off. The led is for indication . wanted a on off but not enough room.  The other push button is to reset the timer counters. Added a 6min and 9min limit that stops the clock at those times.
