Switch Current and Voltage Ratings
Non switching:  You can apply 50VDC with a load current of 100mA as long as you don't change the state of the switch.

Switching: You can switch the load on and off all day with an applied voltage of 5VDC and a load current of 100mA.

Minimum:  The applied voltage should exceed 20mVDC and the load current should be at least 1uA in order to guarantee reliable switching.

With an applied voltage of 3VDC and a load current of 100mA you should be fine.
