ABSTRACT:
A slidable element is provided for easy positioning in a guide slot when a handle is withdrawn. A handle 40 is inclinably provided on a mount body 35 bearing a movable electrode 31 by a support shaft 45. The support shaft 45 is loosely movable with respect to the mount body 35 by being fixed to the handle 40 and being inserted through oblong holes 42 formed in bearing portions 41 of the mount body 35. In order to withdraw the handle 40, it is necessary to position slidable projections 70 at the bottom ends of linear portions 75 of guide slots 74 while the handle 40 is pulled up. Since the support shaft 45 is movable upward within the oblong holes 42, the handle 40 can singly be pulled up while the movable electrode 31 is still engaged with the fixed electrodes 11a, 11b. During this time, the slidable projections 70 can be positioned and passed through the linear portions 75 of the guide slots 74 with a small force.
