Circuit a line hot wire to the l1 screw. The capacitor allows the coil of the relay to be energized until the capacitor stores a charge thus de energizing the coil. Wire a dpdt rocker switch for reversing polarity.
Constant to momentary output positive inputpositive output relay wiring diagram. The smaller lugs marked and are for the led. Examples of momentary switches push button. Circuit b line hot wire to the l2 screw. Connect wires per wiring diagram as follows. When you need to control a dc motor such as a dc linear actuator you usually need to be able to swap the polarity on the wires going to the motor.
They close when you press the button. Most often momentary switches are best used for intermittent user input cases. Second load wire from load 1 to the a2 screw. Push button switches are the.
