You can change the mode of the roller switch to make it turn off when the lever is pushed in towards the Bit. In "open" mode, it is similar to a refrigerator light. When you open a refrigerator the light is on and when you close the refrigerator the roller switch is activated and the light turns off. When the roller switch's mode switch is set to "close", the signal will not pass through until the lever is pushed in.

Note: The lever can only be pushed in towards the Bit. Do not pull the lever away from the Bit.
