Electronic – ny symbol for Alternate action switch

switchessymbol [~]

There are some switches, that looks like push-button switches, but acts like On-Off switches (i.e. can maintain contact). In one-press they turns-on (and looks slightly deeper), and in next-press, they turns off (and looks slightly higher),
like this one:

I saw them frequently ( in TV-sets, Water purifiers, old radios, etc. )

Now, is there any any circuit- symbol for them?

No. A schematic diagram is concerned only with the electrical behavior of the switch — which sets of contacts are connected in what patterns, such as SPST, DPDT, etc.

The mechanical behavior of the switch is outside the scope of the schematic diagram, so there's no specific symbology associated with it, other than to perhaps put some sort of text note near the electrical symbol. The actual switch is specified in the Bill of Materials (BOM), usually with a specific manufacturer and part number, or a description of the relevant features if a specific part has not yet been selected.
