What are some good reliable toggle switches?

I used Summit Racing® Toggle Switches SUM-G3902 (not cheap at $16 each) for my fuel pump on my build as a safety feature. After 4 years but only a few tens of cycles, the toggle switch failed while I was driving. :( I hadn't used the switch for a while (months?) when it turned off by itself. Rather than clicking when switched, it is loose and floppy. Note that another reviewer had the same issue!! Luckily I could switch it back on, but I'm definitely going to replace it with a better toggle switch!

I'm just asking why you use a toggle to power a pump. More importantly, is it activating a relay or just straight 12v. power. Reason: as you see, they don't last long and putting that kind of amperage draw on a toggle is too much (unless the switch is rated such), which would be a hefty switch. Your loads should always go through a relay. Now having said this, if you have it triggering a relay, I'm not sure why your toggle failed. I use Cole Hersee toggles and relays and have the same toggles in use the past 20+ years. They trigger relays and have not failed.

The toggle switch is activating the relay - it is not in line after the relay to directly power the fuel pump.

Note that another review of this toggle switch is as follows "I literally installed this thing a and maybe toggled it 25 times and now the bar is super loose." - so I think the toggle switch has some quality issues.

I guess that's a pretty poor toggle then if it can't control low amperage trigger voltage. Have you thought of just triggering the pump/relay with ignition on, or is the toggle another type of "safety" item you wanted.

I wanted to be able to turn off the fuel pump by itself as a safety measure but also as a theft deterrent.

Thanks! Those look like quality toggle switches!! 40,000 mechanical cycles!! And not much more than the Summit switch. :)

I bought all my extra switches (and a whole bunch of other stuff!) from McMaster Carr. See: https://www.mcmaster.com/electrical-controls/manual-switches/

I got my switches (and most everything else electrical except the harness) from Delcity (delcity.net). No failures after ten years.

Have you considered letting the key switch activate the fuel pump relay and splicing the toggle switch in line as the theft and safety feature?

Be sure if you put a switch in-line for your fuel pump that it is either working as a switch on the relay activation (trigger) wire or on the ground wire of your fuel pump circuit.

Lucas Look A Likes from Holden Vintage and Classic in the UK.

I ordered all my toggle switches from them. High quality, rated at 15 amps and look original like the Lucas switches when you add their bezel.

One of their switches:

The bezel:
https://www.holden.co.uk/p/toggle_switch_special_bezel

Read the bezel page to see if you need the extra threaded washer for matching the hole size as the Lucas and FFR switches use a larger hole. I bought the bezel and the threaded washer to fit the pre-drilled larger holes. You don't need the threaded washer if you are drilling the holes to fit the switch.

Now, here are some nice 35 amp switches from Ron Francis Wiring:

I can only speak anecdotally .. I used all Carling Tech Toggle Switches.
Here is an example of a one of the simple SPDT
https://www.amazon.com/gp/product/B0195UJNSK/
I have a keyless pushbutton start setup, with a single toggle to turn "on" and "off" the car. so that 1 toggle is switched on/off every time I fire up the car.
The others are the same manufacturer of switch, but they see far less use than the ignition (including a 2 stage off-on-on switch for the headlights).
It's been quite a few "hundreds" of toggles, and it still works and feels just fine.
Even better.. they are not expensive, and I ordered an extra one by accident. So, I technically have a backup on hand.
