Safety Switches NM
In the case of NM safety switches of Design Type 1 (see
page 6), the switching element and actuator form a constructional
and functional unit.
These safety switches are available with 6 different actuator heads:
In this way, the NM safety switches of Design Type 1 offers the
designer and user a maximum degree of flexibility for a broad
range of applications (for examples see page 7).
The hinged switches deserve special attention due to its solid and
hollow shaft versions.
Convenient installation of the solid shaft switch (NM..AL/AK)
into the existing hinge is possible by replacing the hinge pin or by
adding the hollow shaft swtich (NM..AG/AK) to the existing
hing pin (by screwing or pinning).

In the case of NM safety switches of Design Type 2 (see
page 22), the switching element and actuator do not form a design
unit, but are functionally combined or separated upon actuation.
These safety switches are used, for example, for the safeguarding
of removable guards.
In the case of the switches NM..VZA, the separate, triple-coded
actuators protects against tampering with protective function of
the switch.
Installation of Design Type 2 safety switches is simplified with the
side or top actuator entry.
Due to the compact construction of the NM...VZA switch and of
the relevant actuator, they can be used on guard devices with
extremely small door radii (for examples see page 23). To ensure
flexibility of the actuators for imprecise door rails, EUCHNER
supplies actuators with rubber bushings. High-quality, spring-
mounted actuators do not have to be used.
Comprehensive accessories, e.g. door latches with integrated
door handle, screwed cable glands, security screws and
connecting lines, are available for all series NM safety switches
(see page 26).
