How to change keyboard layout to specific language with hotkey in macOS?

How can I change my keyboard layout to English with Caps Lock and change layout to Russian with Shift+Caps Lock?

An old version of Punto Switcher could do this on Windows.

Solution 1:

For the general case of changing input sources via keyboard shortcuts, see this earlier question.

Another approach might be to use the app Ukelele to design a custom keyboard that does what you want, but it would be a lot of work.

If it would be enough to use Caps Lock to switch between English and Russian, you can do this by just checking a box at the bottom of System Preferences > Keyboard > Input Sources.
