Abstract

The warning device has a housing (1), a door (2), a breakable element (4) and a warning device insert, which has a supporting element or a circuit board (8), at least one switching element (5), an actuating device (3), a compression spring (6), which acts on the actuating device (3), and a warning device tray (7). Arranged between the circuit board or the support part (8) and the tray (7) is an actuating mechanism (19), which is formed by an operating lever (9), which is fixed on one side and is pivotally mounted (9a), by an operating element (3) protruding forwards through the tray (7) and by a resilient element (12) at the free end of the operating lever (9b), which is assigned to a switch head (5a) of the switching element (5). The resilient element (12) may be formed by a leaf spring (10) which is fastened on the operating lever (9) and may have a longitudinal cut (10b) so that a switching element (5) is assigned to each of both leaf spring ends. The operating lever (9), the operating element (3) and the resilient element (12) may form the fastening mechanism (19) in one piece. <IMAGE>
