(permanently) until you push it again and it breaks contact - a
toggle action.

lighting systems don't operate in this way. You tend to find these
switches being used for 'bell push' or other signaling applications,
which is why a lot of them to be found in electrical wholesalers
have 'push' or pictures of bells on them! They tend to have a high
push resistance (i.e. stiff) in my experience.

more aesthetic that the plastic clipsal ones and come in a huge range
of finishes (I have the solid metal brushed aluminium type). Pics on
