ESUPPORT Car Marine Blue LED Toggle Switch Dash 4pin Pack of 5

Good value. Functional. The switches arrived in a clear plastic bulk bag without instructions or pin-out information. They are 20 amp 12 volt stitches commonly used on autos, boats and outdoor sport vehicles. You use standard size female blade crimp type connectors, they can be uninsulated connectors because the blade connectors had molded plastic shielding walls dividing/between each blade connector. As viewed from the rear, there are four (4) standard size flat blade (male) connectors on the rear of the switch allowing on-off function with, or without, use of a blue LED pilot light on the front of the rocker switch. The LED can be used as a power on, or device on indicator, or omitted (not used AKA a simple on-off switch) . Looking at the switch with the two (2) blank positions oriented at the top (as in some of the the Amazon vendor item photos), the pins on the LEFT side are for the power in/out, and the pins on the RIGHT side are grounds for the blue LED pilot light. In below instruction set, the UPPER LEFT pin is used as a line or power in, the LOWER LEFT is used as line out or power out to the accessory/device being controlled by the switch. 1) If you want to use the switch only as an on-off switch without the LED pilot light, only use the two LEFT-hand terminals 2) If you want the LED illuminate and function as a "accessory power on" (LED illuminated), ground the UPPER-RIGHT-side blade connector and the LED will come on only when the switch is closed (on) and the accessory is powered/on. Do NOT use the LOWER-RIGHT right terminal in this use. In any case, do not connect both RIGHT-hand terminals to ground, only connect one, or none. 3) If you want the LED illuminate and to function as a "power available" LED illuminated) regardless of switch position (on or off), ground the LOWER-RIGHT blade connector and the LED will come on whenever it has power supplied typically when the vehicle's power system is energized/power is available. When you close the switch (turn it on) the LED stays illuminated regardless of the switch position, as long as vehicle power is on/available. Do NOT use the UPPER-RIGHT right terminal in this use. In any case, do not connect both RIGHT-hand terminals to ground, only connect one, or none.

Perfect. The switches worked well. I used one to add a switch to the ramp light on my enclosed trailer. Durable and the fact that they have plastic dividers between the connections adds a little safety against shorting leads. If I had a complaint, it would be that the terminals aren't marked. Thankfully one of the reviews before mine explained the pin out.

Not much to say about these. They work good for what you need them for in a marine environment. As with anything they will wear out over time and need to be replaced. Seem to have a good quality to them.

As far as I can tell, this is the best price for these types of toggle switches. Installed them into my 04 wrangler, in the rocker switch tray built into the car. That took some modification, because these switches aren't actually designed to fit in the pre-made rocker slots in the TJ model. They will work though, it just required modifying the slots in the car. Had to saw the tops of them open a bit to make more space - these switches are larger than the TJ designed switches. Work well though. Lights are nice. I have to admit - the seller should really put up a diagram to make it easy for wiring. I had to hook it up to my Simpson meter to determine what was what. It would have been a lot more convenient for you guys to just put up a simple diagram. There are a lot of other reviews that ask for the same thing that look pretty old, and it doesn't look like you've done it yet. I would suggest it. Would certainly buy again from you if I need more!

These are of average quality for very inexpensive switches. They are not however, LED. (I'd give it a 4 if i didn't think the LED thing was deceptive) It's still a great deal for 5 switches if it stays at $14 .. but know that they are not illuminated by an LED. There is no LED in the package nor inside the switch. I took one apart, because there was no wiring diagram nor any documentation, and examine and tested the lamp. The indicator lamp in this switch is a regular, plain old, every day, 12volt incandescent lamp. There is no other way to spin that... you can, of course, use it to turn an LED light on and off if you want... but you'd have to supply that LED yourself. The bad... false advertising and slightly higher current draw by the indicator than an LED would be. The good... polarity wont matter as far as the pilot lamp is concerned, where with an LED it would... and, in a dimmed circuit...if connected correctly, it will work nicely. This is technically a DPST or Double Pole, Single Throw Switch, with the lamp wired across the two center terminals. You could wire it a couple different ways... If the intent is to switch the positive side of a circuit, and use the lamp to indicator that the load is powered, power one center terminal, connect your load to the outside terminal on the side you powered, and then ground the other outside terminal.(leaving the other center terminal on the side you grounded unconnected) If the intent is to switch the ground side of a circuit, and use the lamp to indicate that the load is grounded, ground one center terminal, connect your load to the outside terminal on the side you grounded, and then power the other outside terminal.(leaving the other center terminal on the side you powered unconnected) There's a couple other things you could do...but the above two are the most likely scenarios.

Switches worked fine. Looking at the back of the switch with the two unused pin slots oriented to the top, the pins on the left are for the power, and the pins on the right are grounds for the pilot light. The upper left pin is line or power in, the lower left pin is line out to the device being controlled by the switch. The pilot light takes its power from the upper left pin and the upper right pin is an unswitched ground for the pilot light and when grounded the pilot light is always on when power is available at the upper left (line in) pin. The lower right pin, if grounded, turns on the pilot light when the device is switched on. If neither right pin is grounded, the pilot light never comes on and the switch functions as a unlighted single pole switch. You would not connect both right pins to ground.

These are just DPST switches with a incandescent bulb that gets it's power and ground from from the legs on the bottom of the switch. No pins are marked as to what they do. I will be using these to mock up a harness, but I won't be using them. There are some very good switches that these are trying to copy, but they are not a good copy. Blue sea systems or something similar is what you want.

Great for lights and accessories on jeeps boats and side by sides
