Abstract:
An enable switch provided with a contact mechanism having a movable contact which is biased toward an OFF state, in which said enable switch switches the contact mechanism between the ON and OFF states during a period when a manipulation member moves from a non-operated position to an intermediate stop position and during a period when the manipulation member moves from the intermediate stop position to a fully operated position, said enable switch being characterized by comprising:a motion transmission mechanism including a first elastic member of which one end swingably supports the manipulation member in a housing and biases the manipulation member toward the non-operated position in such a manner that part of the manipulation member is exposed to the exterior; wherein the motion transmission mechanism converts a swing motion of the manipulation member from the non-operated position to the intermediate stop position into a motion of switching from the OFF state to the ON state and transmits the switching motion to the contact mechanism, converts the swing motion of the manipulation member from the intermediate stop position to the fully operated position into the motion of switching from the ON state to the OFF state and transmits the switching motion to the contact mechanism, and prohibits transmission of the swing motion of the manipulation member to the contact mechanism during a period when the manipulation member returns from the fully operated position back to the non-operated position.
