tion is reset, and the lamp inside the switch goes out.

tion, the lift arm operation will stop.

position cannot be set.)

set to the FLOAT position, the lift arm is only set to FLOAT and it
does not automatically stop.

returns from the FLOAT position to the HOLD position, the
lift arm operation will stop.
