Technical specifications for the micro-switch

The brake can be equipped with a micro-switch for monitoring the release or wear. The micro-switch can
be integrated into the circuit as an NO or NC contact.
As of June 2012, a new small micro-switch (with UL acceptance) is in use, which is perfectly adapted to
the contour of the brake. The old switch design can be converted by connecting an adapter to the same
threaded holes.
