Abstract:
1. A safety switch box for a control switch of a saw machine which comprises a switch platform and a switch member pivotally extended thereon to operate said saw machine in an on and off manner, wherein said safety switch box comprises: a supporting base adapted for resting on said switch platform, wherein said supporting base has a through slot formed thereon for said switch member passing through; a switch shelter, which has an outer operating side and an inner contacting side, pivotally connected to said supporting base to define a sheltering cavity between said switch shelter and said supporting base for receiving said switch member, wherein said switch shelter is capable of being pivotally folded between an idle position and an operation position, wherein said supporting base, having a U-shaped cross section, further has a base platform defining said through slot thereon and first and second sidewalls upwardly extended from said base platform to define said sheltering cavity within said base platform, and said first and second sidewalls for retaining said switch member within said sheltering cavity, wherein said switch shelter, having a L-shaped cross section is pivotally connected to said supporting base, wherein said switch shelter further has a side arm downwardly extended from a peripheral edge to overlap with said first sidewall of said supporting base; and means for locking said switch shelter on said supporting base at said idle position, wherein at said operation position, said switch shelter is pivotally folded to a position that said contacting side of said switch shelter is adapted for contacting with said switch member to protectively shelter said switch member within said sheltering cavity in position while said saw machine is operating, and at said idle position, said operation side of said switch shelter is pressed to force said contacting side thereof for pivotally pressing said switch member downward to switch off said saw machine, wherein said locking means has a locking groove formed on said first sidewalls of said supporting base and at least a corresponding locking protrusion formed on said side arm to engage with said locking groove so as to lock up said switch shelter with said supporting base at said idle position.
