Common Questions
How do I know which action I need — locking or momentary?
If you need the switch to stay on after pressing (like a power button), choose Locking. If you need it to be active only while held (like a doorbell or a trigger), choose Momentary. Self-locking switches stay in position when pressed; momentary switches return to their default state when released.
Please note: Select your required action (Locking or Momentary) and colour from the variant selector. For AC mains wiring, installation by a qualified electrician is required.
