How to wire a on off on rocker switch?

Wiring an on-off-on rocker switch can vary depending on the specific switch and application, but here is a general guide:

Determine the type of rocker switch you have. On-off-on rocker switches have three terminals or pins on the back, labeled "1," "2," and "3."

Connect the power source to the center terminal (terminal 2) of the switch. This will be the terminal that is connected to the load in the "on" position and disconnected from the load in the "off" position.

Connect the load to either the top or bottom terminal (terminal 1 or 3, respectively) of the switch. This will be the terminal that is connected to the power source in the "on" position and disconnected from the power source in the "off" position.

If you are using the switch to control a DC motor or other device with polarity, connect the positive lead to one of the outer terminals and the negative lead to the other outer terminal.

If the switch has a ground terminal, connect it to the ground wire of your circuit.

Test the switch to make sure it is wired correctly and functions as expected.

It's always a good idea to consult the manufacturer's wiring diagram or instructions for your specific switch to ensure proper wiring. Additionally, if you are unsure about any aspect of wiring an electrical switch, it's best to seek the advice of a qualified electrician or technician.
