Safety switches are used in electric power distribution systems for isolating a load or a portion of the circuit and interrupting the power connection as overloading so as to protect the device to be in safety condition. The switch mechanism has a number of switchblades mounted along a rotatable switch shaft. The shaft is rotated by a handle mounted at one side of the box and coupled to the shaft by a spring toggle mechanism which assures, by snap action, that the switch opens and closes rapidly. A conventional switch device for a power tool generally includes a trigger which is engaged with a trigger assembly. When pulling the trigger, the circuit of the power tool is activated and the tool is operated. Safety switches for isolating a load or a portion of a power circuit in electronics systems are installed within an electronic device to prevent its housing or the internal electronic elements being touched by an unauthorized third party.
