ABSTRACT:
A saw switch box includes a supporting base resting on a switch platform, a switch shelter pivotally connected to the supporting base to define a sheltering cavity between the switch shelter and the supporting base for receiving a switch member, and a locking device for locking the switch shelter on the supporting base at the idle position. In which, at an operation position, the switch shelter is pivotally folded to a position that a contacting side of the switch shelter is adapted for contacting with the switch member to protectively shelter the switch member within the sheltering cavity in position while the saw machine is operating, and at the idle position, an operation side of the switch shelter is pressed to force the contacting side thereof for pivotally pressing the switch member downward to switch off the saw machine.
