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.
