Could someone provide a link to a momentary switch

[edcantu9]

Hello all. I am looking for 25 Amp, heavy duty, single pole, single throw momentary switch online. I could probably go to a electric supplier online but I would rather order it online.

I am having no luck finding it.

Can anyone help?

What voltage spec, 12v or 120volt? You want a push button or a toggle? Inductive or resistive load? Package size? Lots of things go into specing a switch.

Maybe the intended use would help us.

Its for the HF scissor car lift. It is a 220 volt outlet. Looking for at toggle. How would I know if I need a inductive or resistive load.

A guy on youtube stated that he used a 25 Amp, heavy duty, single pole, single throw momentary switch, unfortunately that was all the information he provided.

It is for the power/hydraulic unit that runs the lift. It has a button, but I would rather have a switch to hook my finger around since it is momentary.

Inductive load would be a motor, resistive load would be a heater.

Open up your switch box and show what is in there now, If it is like mine it is not a single pole switch. It operates the pump and a solenoid valve to lift, and the pump and a different solenoid to lower. Unless you have a schematic and have confirmed that the utubber has the exact model I'd suggest caution.

Like the link to mcmaster shows there are a few different sizes, 19mm, 20mm, and others. If you select the correct one then it will fit your panel opening

There are 3 terminals on the back, but only 2 are being used, the third one is empty. I will take pictures tomorrow.

I think this one would work, but I don't understand why it has so many terminals in the back.

.... I don't understand why it has so many terminals in the back.

https://www.amazon.com/dp/B000LFVFA8/?tag=atomicindus08-20

because it's a double pole, double throw .

 

[edcantu9]

because it's a double pole, double throw .

Would it be okay to use if I only use one set of the terminals in the back?

 

[edcantu9]

You figure if I googled "20 amp single pole single throw momentary switch" it would pop up. But no such luck.

 

[edcantu9]

Is this one?

Or a foot switch would be nice, would this one work?

Those aren't very high rated; they're normally used with control circuits, rather than directly controlling a load.

A lot of switches have 6A or 10A max ratings.

If you don't have luck finding a 220V 25A switch, try 220V and 30A, or 250V and 30A.

I'm not having any luck.

I still cannot find a pushbutton switch, but there are some appropriately spec'ed rocker switches at Mouser that might work:

That's not momentary though.

There are also a lot of basic switch modules that might match with momentary button assemblies. That'll take more research than I can spare at the moment.

Use a properly rated contactor, & a pushbutton with NO, normally open contacts

Can you link me one?

Here you go:

Almost what you want. This breaks out both the NO and NC pins for you to choose from. Rated at 25A for 120V/250V AC or 2A at 48V DC.

That being said, if you care about looks or ease of pressure then you might be better off with a slightly more complicated setup of a standard sized pushbutton, 12V wall-wart and a relay. I can diagram the circuit if you wish for the standard pushbutton driving a relay.

^^^ YES!! So much more reliable.

This is the switch I used on the HF scissor lift. It works perfect.
