Abstract: A slide element has legs springable toward and from each other, the legs having pins on their mutually opposed inner surfaces insertable into a hole in the switch actuating lever. The slide element extends longitudinally of the lever, and therebeyond. A blocking element fits over the slide element, and locks it in place, on the lever, and holds it immovably within the blocking element. The blocking element reacts with elements of the switch to hold itself in place, and thus hold the switch lever in position. One form of the device includes a locking lever for mechanically forcing the blocking element down against the switch into blocking position.
