Handling
& Assembly Instructions
Use proper lead clamping or heat sinking techniques to
prevent mechanical and/or heat stress to the glass seal
during bending, cutting, soldering, and welding
Mechanical shock as the result of dropping the reed switch
typically from a distance of greater than 12” may change it’s
magnetic sensitivity and/or destroy the switch
Any form of modification to the switch leads will alter it’s
magnetic sensitivity
