If we wanted to keep the motor running even after the operator takes his or her hand off the control switch es we could change the circuit in a couple of different ways.
Motor circuit switch.
The transistor in this example completes the motor s circuit to ground.
Choose the motor switches that meet your specific requirements.
A transistor can act as a digital switch enabling the arduino to control loads with higher electrical requirements.
We could replace the push button switches with.
Help provide on off control of your motors with motor circuit breakers from grainger.
Most motors require more current and or voltage to operate.
The follow up question of how we may make the motor stop running is a.
Marked motor circuit pullout switch they may be used only in a motor circuit.
Motor branch circuit and at the motor disconnecting means motor controller identification.
The interlock contacts installed in the previous section s motor control circuit work fine but the motor will run only as long as each push button switch is held down.
This example uses a tip120 which can switch up to 60v at 5a.
When used with properly sized branch circuit fuses pullout switches may be used for motor motor circuit and group motor protection.
This circuit is known as a latching circuit because it latches in the on state after a momentary action.
