He could not withdraw from its leads lock ing position to open the the button circuit through 5 and 6, and to thus withdraw his vote after being once cast. The voting circuits could not be opened, and the members 10 could not be moved back into normal position until after the electromagnet 16 is deenergized,and this magnet would be deenergized only by the speaker opening the master switch after the vote had been fully counted and recorded. Turning now to the closing means for the circuit across leads 1 and 2, this will be seen to be substantially identical with that just clescribed for the circuit across leads 5 and 6. it includes a similar pin 9', element 10,
