Abstract

1. An alarm device for doors or windows comprising an electrical contact switch (3) which is arranged in a recess (9) in the door or window frame, being masked at least in an outward direction, and a signal means (5) which is connected to the electrical contact switch (3) and which in the switched-on condition, when the window or door is opened, is set in operation by the electrical contact switch (3), wherein the contact switch (3) has at least two fixed contacts (1, 2) which, when the window or door is closed or locked, can be electrically connected together to close or open a circuit by means of an electrically conductive spring contact (4) which is fixedly connected to the one fixed contact (1), whereby the switched-on signal means (5) is rendered inoperative and when the window or door is opened or unlocked the spring contact (4) is separated from the other fixed contact (2) to set the switched-on signal means (5) in operation, characterised in that the spring contact (4) is in the form of a leaf spring of which one end is connected to the one fixed contact (1) and the other end is freely movable and, when the window or door is closed or locked, is in electrically conducting contact with the other fixed contact (2) and, when the window or door is opened or unlocked, is moved away from the fixed contact (2) by the return spring force and which is arranged behind a cover (10; 45) extending perpendicularly to the direction of movement of the leaf springs, and that a carrier (8, 27) to which the contacts (1, 2, 4, 26) are fixed is adjustable in respect of height with respect to the bottom (19) of the recess (9) in which the contact switch (3) is arranged, by means of screws (20, 21; 30, 31) which are rotatable in the carrier (8, 27) and to which the carrier (8, 27) is held.
