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.

The timer can be an oscillator where a capacitor is prematurely discharged by a pulsating signal already present on the supply lines. The base can include additional means for inhibiting the pulsating signal when a voltage applied to the signalling device either exceeds a predetermined threshold, or changes in polarity, or both.
