FIELD OF THE INVENTION  
       [0001]     This portable device relates to an in-line switch, more specifically, to a switch with a soft glowing light.  
       BACKGROUND OF THE INVENTION  
       [0002]     This invention relates to a novel configuration for a controller which can be used by elderly persons, disabled persons and hospital patients. People usually remove their eyeglasses when in bed and this makes it difficult to find a conventional switch in a darkened room when attempting to locate an electrical device such as a lamp near a bed. Use of this controller overcomes that difficulty. The device uses an illuminated rocker switch, of proven reliability, enclosed in a shock resistant plastic case. The device is connected to a power cord which terminates in a special split plug.  
         [0003]     There are illuminated wall switches available, some with LED lights which cannot be used by persons in bed. There is a portable device made by Lutron Electronics under U.S. Pat. No. 4,104,606 that has a small LED light which is difficult for an elderly person to see in a dark room. The present device has a projection on the case which forms an aperture though which a string may be inserted to suspend the device for use in a sick bed or to childproof a room when appliances such as fans or electric heaters are being used.  
       SUMMARY OF THE INVENTION  
       [0004]     A primary objective of the present invention is to provide a simple, reliable, portable in-line controlling device to be used in a darkened room by elderly or disabled persons who remove their eyeglasses in bed. A further objective of the invention is to provide a device that is easily installed. The device has a minimum of parts which can be manufactured with conventional machinery and is easily assembled.  
         [0005]     Toward these objectives a preferred embodiment is described as follows: A portable in-line illuminated switch enclosed in a shock resistant plastic case having skid resistant plastic feet. The switch is secured between the case and the base plate on assembly. A two conductor power cord, with tinned ends, is inserted in the switch. When the switch is assembled with the case and the base power cord exits the case and terminates in a M/F plug of a well-known type. The male part of the plug is inserted in a power source outlet and a bed lamp or such is inserted in the female part of said plug. A bed lamp may be controlled for bedside use. A further embodiment may be programmed to illuminate a hall or bathroom or such providing a safer environment.  
         [0006]     According to a further preferred embodiment, a portable in-line switching device is provided that comprises: a housing and base of shock resistant material; a main switch constructed at least in part of a translucent shock-resistant material and received in a surface of the housing; an illuminating element contained in the housing for providing a source of light emission through the main switch; and a projection being part of the base defining an aperture for attaching the switching device; wherein the main switch is connected to a power cord terminating in a dual purpose plug and the main switch is operable between an open and a closed switch position by applying an operative force against at least a portion of the translucent shock-resistant material.  
         [0007]     In one variation, the main switch is a rocker switch. In a further variation, the housing is fastened to a base. The main switch may also be a foot-operated switch.  
         [0008]     The main switch may be a push button switch. The base mentioned above may comprise feet for reducing skidding on external surfaces. The feet may be inserted into a plurality of recesses defined in said base. The illuminating element is in electrical communication with the power cord.  
         [0009]     The base may comprise two pedestals with the main switch is mounted on the two pedestals.  
         [0010]     In a variation, the base may comprise a raised area for guiding a power cord from the main switch out of the housing. The base may comprise a further first raised serration and the raised area guides the power cord from the main switch over the raised serration out of the housing. The housing may define a second raised serration opposing the first raised serration for securing the power cord when the housing is fastened to the base. The plane defined by the first and the second raised serration is preferably transverse to the axis of the power cord. Each of the raised serrations may press on a resilient insulation layer covering the power cord when securing the power cord.  
         [0011]     The illuminating element may serve as a beacon for a person in a darkened environment or for use in a bed or in a room where an electric fan or an electric heater is being used.  
         [0012]     The device may further comprise a second switch constructed at least in part of a translucent material and received in the surface of the housing. The translucent material of the second switch has a different colour from the translucent material of the main switch for distinguishing the second switch from the main switch.  
         [0013]     In a further embodiment, this invention also includes a portable in-line switching device comprising: a housing constructed of shock-resistant plastic; a main switch constructed at least in part of a translucent material and received in a surface of the housing; and an illuminating element contained in the housing for providing a source of light for emitting light through the main switch; wherein the main switch is a rocker switch; the housing is fastened to a base, the base comprising two pedestals; the base comprises a projection defining an aperture for attaching the housing to an external object; and feet for reducing skidding on external surfaces.
