ABSTRACT OF THE DISCLOSURE The invention relates to a contact mechanism suitable for application to printed circuits arranged on a board and may be employed in a telephone set comprising push button means. The mechanism consists of a first contact member in the form of a leaf spring having two legs and between these a tongue part, the middle portion of which has an inwardly curved bent part and the lower portion of which has two narrow taps carrying the con- tact elements. The first contact member is placed in upright position along a groove in a bottom plate. A second contact member consists of a small T-shaped metal plate which is fastened oppositely to said taps in a notch of the groove and carries a contact element. The contact mechanism is actuated when a button is depressed whereby a curved part of the button engages the bent part and forces the tongue part to move into contact with the second contact member.
