The switch circuit of electric self-lock/interlock
The switch circuit of electric self-lock/interlock
1.switch featuresThe core part of the switch is made of 4 op-amps LM324, with subtle design, each op-amp has two functions: the voltage comparator and the Schmidt trigger. The voltage range is large, and the stages can be adjusted, if it is added with a neutral gear, it can be the general reset, when the circuit cooperates with a digital circuit, they share a power supply, the input/output LEV conforms to the digital circuit connector LEV, as the input impedance of the op-amp is high, the input current of the switch is low. The touch switch, conductive rubber and film switch can be used as the key.
