Bistable circuit is a kind of circuit we often use. It is always usedas one-button controlling switchin various circuits. Working principle: If N1 input end starts in high level, then N2 output also is in high level, then R2 makes the circuit output the high level stably. At this time, because the N1's output port is in low level, therefore C1 discharges by R1. After pressing down S1, N1's input end changes to the low level, the N2's input rises, the N2's output changes to the low level, then the circuit reverses to output the low level stably, and C1 charges by R1. If pressesing S1 again, the circuit returns to another steady state.
