Note 1: See Figure 1.
Table 2. SS351AT/SS451A Absolute Maximum Ratings
Note 1: 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.

NOTICE
Absolute maximum ratings are the extreme limits that the device will withstand without
damage to the device. However, the electrical and mechanical characteristics are not
guaranteed as the maximum limits (above recommended operating conditions) are
approached, nor will the device necessarily operate at absolute maximum ratings.
