Current draw of lighted toggle switches?


get-the-net

Question

I have a question for you all.

I just put in a new toggle switch bank in my boat which features lighted switches for the bilge,livewell,int lights, running lights, etc. The problem is they stay lit all the time even when each switch is off. Do any of you guys have toggle switches like these and if so do you worry about them running your battery out? I thought I had it solved when I linked all the other switches to the main "power" one so when I shut it off all the other lighted switches went out. But the "power" switch stays lit. Do I need to install an unlighted "master" switch to cut the power from the battery altogether? I feel like I'm just adding more things that can go wrong. For now I unhooked the battery. Any help would be appreciated.

Thank you

I have switches with lights and they only light up when there on and goes off when turned off. Macgyver55 & Val are right I would recheck your wiring, something is not right.

Check the continuity of the switches you most likely are supply battery power to the wrong pin. Two pins should have continuity all the time nomatter what the position of the switch, usually the center pin and the pin on the bottom (bottom refering to the pin under the toggle when off) Two pins will only have continuity with the switch on, usaully the center and top pin. My guess is you have the power from the battery going to the center pin as in the first diagram below. this is the only way I can figure that the switch light could be on all the time. It should be wired like the second diagram. when the switch is open there is no power getting to the light in the switch.

Please remember to always fuse battery power before it gets to the switch.

Personally I like to wire all my switches on the ground side this way all the current is used be the device I am powering leaving little current draw through the switch. The switch stays cool, stand little chance of burning up, and will last a lot longer. Although I have not personally done a lighted switch this way I am pretty shure it would be wired like the third diagram.

    • Truly sorry to hear that duffman! I know that feeling.  Keep the good memories  
    • Chamois passed away this weekend a couple days short of her 13th bday. What a great dog to hang out with here at home and on distant adventures. Gonna miss ya big time my little big girl.
    • Sounds pretty sweet, alright. I will check them out, thanks.
    • If you really want to treat your wife (and yourself) with a remote operated trolling motor, the Minn Kota Ulterra is about easy as it gets.  Auto stow and deploy is pretty awesome.  You just have to turn the motor on when you go out and that the last time you have to touch it.   24V 80lb.  60 inch shaft is probably the right length for your boat.  They ain’t cheap - about $3k - but neither one of you would have to leave your seat to use it all day.
    • Wanderer, thanks for your reply. I do intend for it to be 24 volt, with a thrust of 70-80. Spot lock is a must (my wife is looking forward to not being the anchor person any more).  With my old boat we did quite a lot of pulling shad raps and hot n tots, using the trolling motor. Unlikely that we will fish in whitecaps, did plenty of that when I was younger. I also need a wireless remote, not going back to a foot pedal. We do a fair amount of bobber fishing. I don't think I will bother with a depth finder on the trolling motor. I am leaning toward moving my Garmin depth finder from my old boat to the new one, just because I am so used to it and it works well for me. I am 70 years old and kinda set in my ways...
    • Dang, new content and now answers.   First, congrats on the new boat!   My recommendation is to get the most thrust you can in 24V, assuming a boat that size isn’t running 36V.  80 might be tops?  I’m partial to MinnKota.     How do you plan to use the trolling motor is an important question too.     All weather or just nice weather?   Casting a lot or bait dragging?   Bobber or panfish fishing?   Spot lock?  Networked with depth finders?  What brand of depth finders?
    • We have bought a new boat, which we will be picking up this spring. It is an Alumacraft Competitor 165 sport with a 90 horse Yamaha motor. I will be buying and installing a trolling motor,  wondering if I can get some recommendations on what pound thrust I will want for this boat?  Also, I will be selling my old boat, is there a good way to determine the value on an older boat ( mid-80's with a 75 horse 2-stroke  Mariner motor)  I will appreciate any help with these questions.
