The AMS-37 is a UL-listed reed
switch. The construction is basically the same as our AMS-39 including
all materials and hardware. It is made in gray only and is designed for
closed circuit systems.
The reed switch itself is 2
inches long and meets all specifications. The magnet is made of ALNICO 6
and is approximately 3 inches long. The AMS-37 reed magnetic switch is
designed for rugged use and can be installed on any opening. The
mounting holes in the case have been designed so that the head of the
screws are recessed, making a neater installation.
