Abstract
The four-states warning switch is a special warning device of exceptional features. One of these features, allows the user to send an initial signal, in case he only suspects that he may be attacked, assaulted, go into a coma or may face a danger of any other type. He does so by pressing the device'"'"'s handle, closing a “suspicion circuit” that transmits a “suspicion signal” to a security office, a police station, an ambulance or a doctor'"'"'s clinic. The user then shifts the handle rightwards while it is still pressed, bringing it to a position, where the device is ready to automatically close a warning circuit in case he releases the handle. This is the second important feature of the device, for if the user releases his/her hand involuntarily in case of an attack or in case he becomes unconscious, a warning signal is automatically transmitted. On the other hand, the user can bring the device back to its “idle state” manually from the “suspicion state”, whenever he feels safe. However, besides these two exceptional features, the device also keeps its prime feature as a direct warning facility. The user can simply bring the device to its “direct warning state” by shifting the handle leftwards without pressing it. He/she benefits from this feature of the device in case of a sudden attack or on facing an unexpected danger.

U”
shape opening wherein said bar fits smoothly on reaching the right end of said slot on pressing said handle and shifting said actuating cylinder element rightwards so as to activate said second push-button switch by said piston extension,f. an activated only when pressed third push-button switch, electrically connected to said second electric circuit and connected in parallel to said second push-button switch, fixed to inner surface of said housing thereat a spot facing said protrusion of said actuating cylinder element so as to activate it by shifting said actuating cylinder element leftwards until said protrusion presses said third push-button switch. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12)
in first setting, said four-states warning switch is in its off state, said handle is not pressed, said piston extension is inside said groove positioned at the right end of said groove;
in second setting, said handle is pressed to activate said first push-button switch;
in third setting, said handle is moved rightwards while being pressed until said bar reaches right end of said slot;
in fourth setting, said handle is released to inactivate said first push-button switch and activate said second push-button switch;
in fifth setting, said handle is moved leftwards to activate said third push-button switch.

5. A four-states warning switch of claim 4, wherein said slot in said housing having circular openings at two spots;
- whereby said first setting and said second setting of said handle taking place at the first spot, while said third setting and said fourth setting of said handle taking place at the second spot; and
said bar having larger clearance at said two spots than the clearance between said bar and the rest of said slot, allowing the user to feel where to locate said handle without looking.
- whereby said first setting and said second setting of said handle taking place at the first spot, while said third setting and said fourth setting of said handle taking place at the second spot; and

6. A four-states warning switch of claim 1, further comprising:
additional push-button switches fitted beside said second push-button switch;
allowing for extra warning functions or signals when required, said additional push-button switches are of a split type, so that said bar passes through them to the required position; and
