Solenoid switches are utilised for the control of large current circuits with a low current switch. These devices contain a high-current switch, which is controlled by a magnetic actuator called a solenoid. When a small current flows through the solenoid, the solenoid core will move, forcing the high-current switch to the closed position. The size of the solenoid determines the number of terminals, which are typically four. Two terminals are for the high-current circuit, while the other two are the low-current terminals of the solenoid.
Step 1
Please locate the high-current switch terminals on the solenoid switch. Please refer to the documentation supplied with the solenoid switch for the location of the aforementioned terminals.
Step 2
Cut two pieces of black wire and strip half an inch of wire off of each end of both wires. Connect one end of the first black wire to the negative terminal of the 12-volt battery. Connect the other end of that wire to one of the high-current terminals on the solenoid switch.
Step 3
Connect one end of the second black wire to the second high-current terminal of the solenoid switch. Then connect the other end of that same wire to the negative terminal of the DC motor.
Step 4
Cut one piece of red wire and remove approximately half an inch of insulation from each end. Connect one end to the positive terminal of the DC motor and the other end to the positive terminal of the 12-volt battery. This concludes the configuration of the high-current circuit.
Step 5
Cut two pieces of black wire and strip half an inch of insulation from each end of both wires. The first wire should be connected to the first low-current terminal on the solenoid switch. The remaining end should be connected to one of the two terminals on the 6-volt switch. The second 6-volt switch terminal should be connected to the negative side of the 6-volt battery.
Step 6
Position one red wire between the positive terminal of the 6-volt battery and connect the other end to the second low-current terminal on the solenoid switch. This concludes the configuration of the low-current circuit.
Please ensure that the 6-volt switch is set to the 'ON' position, after which the DC motor should start running.
