A safety switch device includes a case with a switch pivotally engaged with an open top of the case and a ramp defined in an inside of the case. Two terminals are extended from the bottom of the case and a bimetallic plate having a first end fixed to one of the terminals. A distal end of the bimetallic plate is located above the other terminal. A pull rod is pivotally connected to the switch so as to lift the bimetallic plate by a hook portion thereof when switching to "OFF" status. A control member has a first end pivotally connected to the switch member and a probe extended from a second end of the control member. The probe is movably engaged with the ramp and the second end of the control member is movably located above the second end of the bimetallic plate.
