ABSTRACT:
The invention relates to an emergency switch for an exercise apparatus having a housing, a safety plug and a microswitch. The safety plug passes through an insertion slot of the housing and is inwardly inserted to the inside of the housing for an electric connection by means of the contact of the distal end of an extension part of the safety plug to a contact key of the microswitch. Meanwhile, an electric disconnection is created when the safety plug is extracted. In addition, a cut-off button with a push rod is interposed between the safety plug and the microswitch. Besides, the cut-off button projects outwardly from the housing. When the cut-off button is pressed down, the push rod makes use of its slanting guide face to separate the safety plug from the contact key of the microswitch into a disconnection state.
