An electric door opener with a trimmer actuatable by an armature and a mat coil. The trimmer is adjustably positioned for the release or locking of a door opener latch. The door opener is useable as an electric no-load current door opener and as an operating current door opener because a selector device is provided to switch the armature-trimmer system between no-load current movement positions and operating current movement position.
