Embodiment Construction

[0024] Referring to the accompanying drawings, an electrical switch 100 shown is an embodiment of the present invention, wherein the switch 100 is in the form of a rocker switch, comprising a rectangular plastic housing 110 and an oval plastic operating rocker 200, which supports Within housing 110 is provided for pivotal movement between an inoperative position (FIG. 1) and an operative position (FIG. 2). The casing 110 has an oval top opening 112 for exposing the rocker arm 200 for easy rocking by the user. The rocker arm 200 has a rod body 210 including a transparent outer cover 212 and is equipped with a neon bulb 230 having an operating voltage such as 12V for lighting to indicate that the rocker arm 200 is in an operating position. A resistor 240 is provided in the housing 110 for being connected in series with the bulb 230 so that the bulb 230 can work at 12V.

[0025] The switch 100 includes three fixed contacts 120A / B / C, which are generally arranged as flat contact p...

Abstract

An electrical switch, such as a rocker switch, includes a casing, three fixed contacts, each contact having an inner end, and an operating rocker movable between an operating position and a non-operating position. The switch includes a moving contact movable by the rocker to make and break electrical connection between the inner ends of a first pair of the fixed contacts (connectable to a load and a power source) while the rocker is in the operating and non-operating positions, respectively. Also included are a light bulb, lighting to indicate when the rocker is in the operating position, and an associated resistor. The light bulb and resistor are connectable in series across the inner ends of a second pair of the fixed contacts (connectable to a power source) when the rocker is in the operating position. The resistor is fixed, has a body, and has first and second terminals. The first terminal is a contact pad on the body, in direct engagement with the inner end of one of the fixed contacts of the second pair of fixed contacts for electrical connection to the fixed contact, and is fixed in position. The resistor is preferably a surface mounted device resistor.

Description

technical field [0001] The present invention relates to an electric switch provided with a small light for indicating the on state. Background technique [0002] Electrical switches of this type are well known to those skilled in the art, ie where the light bulb often requires a resistor in series in order to function correctly. The resistors take up space, and thus inevitably increase the size of the switch. Additionally, the connection and fixing of resistors often involves bending or soldering during installation. [0003] The subject invention seeks to alleviate or at least reduce such problems by providing such an improved electrical switch. Contents of the invention [0004] According to the present invention, there is provided an electrical switch comprising a housing, at least three fixed contacts extending from the interior of the housing to the exterior of the housing, each of said contacts having an inner end portion, and an operably parts, which are used to ...
