!include works on sensor, but not switch?

ESPHome

These two !include statements look identical, and both .yaml files are precent at its referred location.

sensor:
  - <<: !include sensor/uptime.config.yaml

switch:
  - <<: !include switch/restart_switch.config.yaml

In my config.yaml I refere to packages like this

packages:
  device_base: !include common/device_base_mhetesp32minikit_Quinled_dig_uno.yaml

And within device_base_mhetesp32minikit_Quinled_dig_uno.yaml I have included two yaml (se above).

For some reason the switch does not show up after flashing the ESP. The WiFi signal sesor do show up, though.

The switch does show when defined directly in config.yaml

WiFi signal sensor as defined in sensor/uptime.config.yaml

- platform: wifi_signal
  name: ${friendly_name} WiFi signal
  update_interval: 300s

Restart switch, as defined in switch/restart_switch.config.yaml

- platform: restart
  name: ${friendly_name} restart
  id: restart_switch
