As the soft-touch control CM that two close contacts that metal is touched with hand are formed, the charging electricity on the first capacitance C1
The input terminal that the second NAND gate A2 is added to by human body resistance is become high level by lotus, eventually lead to third NAND gate A3,
Third NAND gate A4 exports high level, the first triode VT1, the second triode VT2 is connected, relay K suction units, contact is closed
It closes, controllable load work.Due to being connected between the first NAND gate A1 and the second NAND gate A2 by second resistance R2, so by
First capacitance Cl is supplied to the high level of the second NAND gate A2 input terminals that will keep, even if hand has left soft-touch control CM,
Circuit can still keep this state, until soft-touch control CM by touching again.
When relay K maintains suction unit state, the input terminal of the first NAND gate A1 is low level, and the first capacitance C1 will pass through
First resistor R1 and the first NAND gate Al discharge into 0V or so.
When soft-touch control CM is touched again, 0V voltages on the first capacitance C1 through human body resistance be added to second with it is non-
The input terminal of door A2 makes circuit be restored to original state, i.e. the first triode VT1, the second triode VT2 cut-off, relay again
Device K discharges, and contact disconnects.
