Abstract
A manual call point having a housing base (1), a cover and an alarm insert with a fragile panel (4), a printed-circuit board (3), a switching element (6) and an actuating mechanism. The actuating mechanism for the switching element (6) is formed by a pivoting lever (7) resting on a lateral edge of the panel (4), the pivoting lever (7) pressing on the switching element (6) in the normal state of the manual call point and holding the switching element (6) in a closed position. When the panel (4) is smashed the pivoting lever (7) pivots, so the switching element (6) is opened. The switching element (6) is arranged on the printed-circuit board (3) and comprises a flexible end switch. The manual call point also contains a device for triggering a test alarm comprising a switching lever (9) to displace the panel (4) until the pivoting lever (7) is released and comprises a member (10) to actuate the switching lever (9).
