The wiring diagram below will demonstrate how to to wire and power this 12v 20amp on on off 3 way carling contura rocker switch. Most often momentary switches are best used for intermittent user input cases.
Edn Latching Power Switch Uses Momentary Pushbutton
Momentary contact switch wiring diagram. The capacitor allows the coil of the relay to be energized until the capacitor stores a charge thus de energizing the coil. Contactor breakers limit switch no static control standard elementary diagram symbols. Examples of momentary switches push button. The resistor bleeds off the charge of the capacitor when positive voltage is removed from the other side of the coil. Switches with two pilot lights. This rocker is perfect for an engine offrunstart switch.
Switches with two pilot lights. Push button switches are the. The smaller lugs marked and are for the led. You will need to wire a current limiting resistor in series as described in the product description. But the switch is a pretty straightforward momentary switch. Diagram f diagram g1 diagram g2 b l 2 4 3 b l 2 4 36 b l 2 4 36 jumper single pole sp double pole dp switch wiring diagrams diagrams represent both momentary contact or maintained contact switches.

A double pole double throw switch is used for this purpose but you have to wire it up correctly. Constant to momentary output positive inputpositive output relay wiring diagram. Stuff like reset or keypad buttons. Connect wires per wiring diagram as follows.
First load wire from load 1 to the a1 screw. Wire a dpdt rocker switch for reversing polarity. Circuit b line hot wire to the l2 screw. Typical wiring diagrams for push button control stations 5 explanation of symbols momentary contact push button auxiliary contacts operate when operating coil of contactor. To convert connect jumper wire from terminal 3 to terminal 6 and connect terminal 4 to ground diagram f diagram g1 diagram g2 b l 2 4 3 b l 2 4 36 b l 2 4 36 jumper single pole sp double pole dp switch wiring diagrams diagrams represent both momentary contact or maintained contact switches. Momentary switches are switches which only remain in their on state as long as theyre being actuated pressed held magnetized etc.
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. Depressing button opens and parent switch does. Second load wire from load 1 to the a2 screw. They close when you press the button. Circuit a line hot wire to the l1 screw. Momentary contact push buttons maintained contact.
The two thicker lugs in the bottom of the photo below are the momentary switch contacts.
