I need to order several of these switches for my layout accessories. They come with Lionel accessories and have the feature of operating either as a momentary push on or if you slide it forward it remains in the on position. I want just generic (not Lionel).
What is the real name for these type of switches so I can order them from Digikey or Frye's or... I would prefer a Forum Sponsor if possible.
Thanks in advance for any help you can give.

So that looks like the Lionel 5903-1.
I am not aware of a "generic" term/name for on-off switch that can be activated either momentary or toggle. Electrically speaking this is just 2 SPST switches in parallel. Given the somewhat large footprint, I'd think the economical and practical route is to individually find a suitably sized momentary SPST and slide/toggle SPST and pair them.
Thanks Stan, Good information, I'll look into that solution.

Well, there are SPDT center off switches that are spring loaded in one direction. Wiring both of the sides of the switch together will allow a momentary or constant activation.
Thank you GRJ, that's the nomenclature I was looking for. Much appreciated.
John
The nomenclature for a switch that GRJ describes would be SPDT ON-OFF-(ON). The () around "ON" indicates it's of the momentary ilk.
If it's two parallel switches, one momentary and one toggle. It would be a SPST OFF-(ON) paired with a SPST OFF-ON.
google spdt on-off-(on)...zillions of hits such as:
Thank you Stan, that helps me a lot. Searching I will go...

Here is an example, this one is double pole, but you just use one side.
