Abstract

The present invention relates to a safety switch device comprising a housing and a handle pivotally connected to the housing via a pivot. An electric switch is accommodated within the housing. A safety press-button is slidably provided on the housing. A pressing member is fixedly mounted on a slideable rod in the housing. An internal portion of the handle presses against the slidable rod. The slidable rod lies in a guiding groove on the interior of the housing. A clearance between the slidable rod in the guiding groove and the edge of the guiding groove is sufficient to advantageously permit the slidable rod to swing in the guiding groove when the safety button is not depressed. Irrespective of whether the safety press-button is depressed or not, the handle can always be rotated about the pivot so that the risk of damage by accidental operation of the handle or safety press button is eliminated.
