The voltage band switch, according to this invention, comprises an electric coil for receiving a fluctuating input voltage supply from a source; a spring-loaded member; a main electrical terminal provided for the member; and spaced auxiliary electrical terminals disposed adjacent the main terminal, corresponding to predetermined bands of input voltage fluctuation values, whereby the main terminal of the moving member, while establishing contact with any auxiliary terminal, closes a control circuit provided therefor, to produce an audio or visual signal, and thus react to the value of the corresponding input voltage band.
This invention will now be described with reference to
the accompanying drawings which illustrate, by way of
example and not by way of limitation, two of possible
embodiments of the voltage band switch
proposed herein.
Fig. 1 illustrating a reciprocating movement of the
member

and
Fig. 2 illustrating a rotary (angular) movement of the member.
The voltage band switch proposed herein is applicable to both a.c. and d.c input voltage supply In Fig. 1, C is a an electric coil and P is a spring-loaded member associated with the coil. The spring is indicated by S. The member is, optionally, provided with a damper D. The fluctuating input supply voltage is received by the coil C and the resulting flux produced at the said coil makes the member P move reciprocably.
In Fig. 2, C is a an electric coil and P is a spring-loaded member associated with the coil. The spring is indicated by S. The member is optionally provided with a damper D. The fluctuating input supply voltage is received by the coil C. Two magnets J are provided on either side of the coil and the resulting flux produced at the said coil makes the coil move angularly, causing the member P also to move angularly.
A main electrical terminal M is provided for the member

p. As the input voltage applied to the coil C fluctuates, the member P moves to and fro with respect to the coil (Fig.l) or angularly (Fig.2>.
Spaced auxiliary electrical terminals Ml M2 M3 are disposed adjacent the main terminal M, corresponding to predetermined bands VI V2 V3 of input voltage fluctuation values, whereby the main terminal M of the moving member P, while establishing contact with any one auxiliary terminal, say, lil closes a control circuit provided for the said auxiliary terminal to indicate and react to the value of the corresponding input voltage band as VI. Similarly for other voltage bands V2 V3 corresponding to auxiliary terminals M2 M3. VMin and VMax are the minimum and maximum voltage values.
The member is springloaded at S to enable it to move up and down. D is a damper for damping the member osci11 at ions.
As the main terminal M establishes contact with any one auxiliary terminal, a corresponding electrical control circuit closes and causes a signal, audio or

visual, to be produced indicating the voltage band value VI or V2 or V3 as the case may be. The operator is thus in a position to react manually to the situation.
Alternatively, or in addition to the foregoing, it is possible to have any such circuit equipped with electrical, electronic or electro-mechanical control means for shutting off power supply to the electric machine receiving the input supply voltage whenever a given circuit is closed by the main terminal. The terms and expressions in this specification are of description and not of limitation, there being no intention to exclude any equivalents of the features illustrated and described but it is understood that various other embodiment of the switch proposed herein are possible without departing from the scope and ambit of this invention
