In electrically adjustable hospital and nursing beds there is a varying need for blocking certain adjustments of the bed. This blocking option is incorporated in the handset for the bed. The handset comprises a plurality of electrical switches (7) having an axially movable activating means (7") in a housing (7'), said activating means protruding a distance from the top of the housing. Above the activating means there is a likewise axially movable key which when being pushed down toward the switch steps on the activating means and presses it inwards toward the housing to activate the switch. A blocking means (12) may be moved from a parking position to a locked position, in which it partly rests on the upper side of the housing of the switch and partly serves as a stop for the overlying key at a level above the activating means of the switch in the rest position. |
