Other designs for power controls were considered, but the one described above was chosen 

 primarily for expediency. An SCR (silicon controlled rectifier) circuit was considered, but time 

 did not permit a circuit to be designed and developed which would carry 30 amperes at 12 volts 

 while providing continuously variable power. 



The general power-control box design, applicable both to the battery and ac power-control 

 boxes, is shown in Fig. 116. An ac power-control box is shown, but the dc box is identical ex- 

 cept for the electrical input connector. 



Fig. 116. Electrically heated suit power con- 

 trolbox, ac power. The upper switch controls 

 power level; the lower switch selects heat to 

 hands and feet or to the full suit.
