There are two switch materials. The completely non–metallic version is designed to operate within
an MRI environment where high magnetic fields would interfere with any electronic switch. The
switch may be safely used within the MRI bore because it is immune to the magnetic field as well
as invisible to the imaging process. It is also an ideal switch for deployment in highly corrosive
atmospheres. Meanwhile, the industrial version employs a metallic non-magnetic spring and can
work over a wider temperature range. The optical signal levels are rated inherently safe, allowing
the system to be safely deployed in various explosive atmospheres or hazardous locations.
In addition, there are two optical circuit configurations. The Normally Open (NO) layout
corresponds to an optical circuit that is open until the microswitch is depressed; the Normally
Closed (NC) layout corresponds to an optical circuit that is closed until the microswitch is
depressed.
