What is a momentary SPST Push Button Switch?

Question

I want to buy a switch (push button) where you press it to break the circuit and then press again to connect the circuit.

However, I'm not entirely sure. I only want to use this for a basic circuit, and I mean really basic, so don't worry about anything there.

Single Pole (SP) single Throw (ST) is s asimple switch.. When it is momentary, one usually chooses a switch that is Normally Open (NO). Then there DT types where one side is NO and the other NC (normally Closed) — D.A.S., Commented Dec 3, 2012 at 13:25

SPST NO (Normally Open) Momentary switch is exactly what is inside a computer keyboard - press for on, let go for off.

It sounds like you are looking for a Latching switch (works like a ballpoint pen) instead of Momentary.

If you can only find one with more poles or features (DPDT) it'll do the job - just ignore the extra features.

A brief look shows this from the same seller, I suspect he has others...

\$\begingroup\$ Hi again, I purchased this: ebay.com.au/itm/… and the switches arrived but they are the keyboard style switches :( is this a misteak by the seller? becuase the item page says it is a latching switch.. i want to know wether i should dispute this with the seller or not. Thanks in advance :) \$\endgroup\$

\$\begingroup\$ I would let the seller know the switch is not as described. Refer to this thread if need be. Give the seller a chance to fix the problem. But I would have expected you could find electronic parts closer than Hong Kong! The name Dick Smith comes to mind (and I've never been to .au! :-) \$\endgroup\$
