TELEPHONE HOOK SWITCH WITH ELASTOMERIC CONTACT MEMBER Abstract of the Disclosure A telephone hook switch uses an elastomeric member as the contact making member. A hook switch has a pivotally mounted actuating member having two levers extending in opposite directions, one on each side of the pivot axis. One lever is moved by the positioning, and removal, of a handset, the actuating member being biased to a particular pivotal direction, The other lever presses on a deformable projection in the elastomeric member. Depression of the projection causes an electrically conducting layer to move into contact with contact areas of a switch position on a printed circuit board. - i -
