Design a control circuit so a 24 V relay , start button, and a stop push button (on/off with memory) operates an electromechanical relay to control a 230 V solenoid Next, Redraw the previous circuit and add a 24 V red lamp to indicate the relay coil is on, a 230 V yellow lamp to indicate the solenoid is on, green lamp to indicate the solenoid is off. Use only one relay, which has multiple contacts.
