Abstract

A slide switch comprises a plurality of sets of aligned terminals, each set comprising at least a center terminal and two end terminals, one to either side of the center terminal and aligned along a common axis therewith, and a plurality of elongate slides respectively associated with the sets of terminals. The slides are of sufficient length to engage the center terminal and only one of the associated end terminals. An actuator mounts the slides for movement between a first position wherein the slides electrically couple each of the center terminals with one of its associated end terminals and a second position wherein the slides electrically couple each of the center terminals with the other of its associated end terminals. A light emitting element has a pair of electrodes and is responsive to a given voltage across the electrodes for emitting light. The actuator comprises an actuator body having a recess for mounting the light emitting element therein for observing the presence or absence of light therefrom during operation of the slide switch, and guides for guiding the pair of electrodes into position for electrically conductive contact respectively with the selected ones of the slides.

Claims

1. A slide switch comprising:

a plurality of sets of aligned terminals, each said set comprising at least a center terminal and two end terminals, one to either side of said center terminal and aligned along a common axis therewith;

a plurality of elongate slide means for slidably engaging predetermined ones of said terminals and respectively associated with said plurality of sets of terminals, said slide means being of sufficient length to engage said center terminal and only one of the associated end terminals;

actuator means including means for mounting said slide means for movement in unison with said actuator means between a first position wherein said slide means electrically couple each of said center terminals with one of its associated end terminals and a second position wherein said slide means electrically couple each of said center terminals with ther other of its associated end terminals;

light emitting means having a pair of electrodes and responsive to a given voltage across said electrodes for emitting light;

said actuator means further including an actuator body having a recess for mounting said light emitting means therein for observing the presence or absence of light therefrom during operation of said slide switch; and

guide means for guiding said pair of electrodes into position for electrically conductive contact with selected ones of said plurality of slide means;

wherein said terminals comprise generally flat, rectilinear upstanding members, wherein said slide means comprise elongate members which are generally U-shaped in cross-section for complementary slideable, wiping engagement over protruding end portions of said terminals, and further including tubular socket members located on external side surfaces of ones of said elongate U-shaped members comprising said selected ones of said plurality of slide means for egaging said electrodes.

2. A slide switch according to claim 1 and further including a substantially flat, rectangular base plate for mounting said sets of terminals.

3. A slide switch according to claim 2, wherein said actuator body includes a pair of inwardly facing elongate channels for slideably engaging oppositely laterally outwardly facing edges of said base plate.

4. A slide switch according to claim 3 wherein said channels are provided with camp-like lead-in surfaces to facilitate engagement thereof with said base plate edges.

5. A slide switch according to claim 1, wherein said mounting means comprise a plurality of parallel elongate mounting slots formed in said actuator body, each for mounting one of said slide means therein.

6. A slide switch according to claim 5 wherein said light emitting means comprises a body;

wherein said pair of electrodes comprise elongate leads depending from said body in spaced parallel condition; and

wherein said guide means comprises a pair of substantially straight and parallel through apertures extending from said recess to ones of said mounting slots which mount said selected ones of said slide means for guiding each of said elongate leads in a substantially straight path to one of said selected ones of said slide means substantially without bending of said electrodes.

7. A slide switch according to claim 5 wherein at least one of said elongate slots further includes stop surfaces at opposite ends thereof for defining limits of slideable movement of said actuator corresponding to said first position and said second position respectively.

8. A slide switch according to claim 1 wherein said light emitting means comprises a light bulb.

9. A slide switch according to claim 1 wherein said light emitting means comprises a light emitting diode.

10. A slide switch according to claim 1 and further including a translucent cap overlying said recess and the light emitting means therein.
