Note 2: All the parameters are tested under the 25

typical value.

Note 3: The magnetic field strength (gauss) required to cause the switch to change state (operate and release) will be as specified in

the magnetic characteristics. To test the switch against the specified magnetic characteristics the switch must be placed in a

uniform magnetic field.
