+### Push button / Momentary switch
+You can set the physical relays to be `on` only while the hardware buttons are pressed, and then back to `off` when the buttons are released:
+
+```yaml
+binary_sensor:
+  # Left button custom action: Push button / Momentary switch - Relay 1
+  - id: !extend left_button
+    on_click:
+      then:
+    on_press:
+      then:
+        switch.turn_on: relay_1
+    on_release:
+        switch.turn_off: relay_1
