The mechanism further comprising an actuation member extending substantially perpendicular to the locking member (80) so as to be displaceable transversely with respect to the locking member (80) and engagable therewith to effect cam engagement between a cam surface (300) of the actuation member and a cam surface (90) of the lever member (80) upon such transverse displacement of the actuation member, so as to pivotally displace the locking member (80) out of engagement with the switch (12).
