Abstract

A slider assembly is for an electrical switch such as, for example, a dimmer switch. The dimmer switch includes a switching member and a housing member. The housing member overlays the switching member and includes an exterior surface, an interior surface, and an elongated slot. The slider assembly includes a slider structured to cooperate with the switching member. The slider includes an interface portion and an attachment portion. The attachment portion extends through the elongated slot of the housing member. The interface portion is movably disposed on the exterior surface of the housing member. A shutter is coupled to the slider. The shutter includes a plurality of resilient elements structured to engage the interior surface of the housing member, thereby creating a friction force associated with movement of the slider.

First claim

What is claimed is:

1. A slider assembly for an electrical switch, said electrical switch including a switching member and a housing member overlaying said switching member, said housing member comprising an exterior surface, an interior surface, and an elongated slot, said slider assembly comprising:
a slider structured to cooperate with said switching member, said slider including an interface portion and an attachment portion, said attachment portion being structured to extend through said elongated slot of said housing member, said interface portion being structured to be movably disposed on the exterior surface of said housing member; and
a shutter coupled to said slider, said shutter including a first resilient element and a second resilient element each structured to engage the interior surface of said housing member, thereby creating a friction force associated with movement of said slider, said shutter being separate and distinct from said slider,
wherein said slider is a single-piece molded member,
wherein said shutter is a single-piece molded member,
wherein said slider is removably coupled to said shutter,
wherein said shutter further includes a first end and a second end disposed opposite and distal the first end, the first end and the second end being disposed on an axis parallel to said interface portion,
wherein said first resilient element extends from the first end toward said second resilient element and said interface portion, and
wherein said second resilient element extends from the second end toward said first resilient element and said interface portion.

2. The slider assembly of claim 1 wherein said interface portion of said slider comprises an elongated molded portion; and wherein said elongated molded portion includes a plurality of ribs or serrations.

3. The slider assembly of claim 1 wherein said shutter comprises a first side, a second side disposed opposite the first side, and an elongated slot disposed between the first end and the second end and extending from the first side toward the second side; and wherein the elongated slot of said shutter is structured to substantially align with the elongated slot of said housing member.

4. The slider assembly of claim 3 wherein said attachment portion of said slider comprises a first resilient prong extending outwardly from said interface portion and a second resilient prong extending outwardly from said interface portion opposite and spaced from said first resilient prong.

5. The slider assembly of claim 4 wherein said shutter further comprises a mounting portion disposed on the second side; and wherein said first resilient prong and said second resilient prong are structured to extend through the elongated slot of said housing member and through the elongated slot of said shutter to removably engage said mounting portion of said shutter.

6. The slider assembly of claim 5 wherein said mounting portion includes a first edge and a second edge; wherein said first resilient prong removably engages the first edge; and wherein said second resilient prong removably engages the second edge.

7. The slider assembly of claim 3 wherein said first resilient element is a first molded spring element extending outwardly from the first side; and wherein said second resilient element is a second molded spring element extending outwardly from the first side opposite and spaced from the first molded spring element.

8. The slider assembly of claim 7 wherein said first molded spring element is disposed between the first end and the elongated slot of said shutter; and wherein said second molded spring element is disposed between the second end and the elongated slot of said shutter.

9. The slider assembly of claim 8 wherein said first molded spring element and said second molded spring element are structured to exert a bias against the interior surface of said housing member to create said friction force associated with movement of said slider.

10. An electrical switch comprising:
a switching member;
a housing member overlaying said switching member, said housing member comprising an exterior surface, an interior surface, and an elongated slot; and
a slider assembly comprising:
a slider cooperating with said switching member, said slider including an interface portion and an attachment portion, said attachment portion extending through said elongated slot of said housing member, said interface portion being movably disposed on the exterior surface of said housing member, and
a shutter coupled to said slider, said shutter including a first resilient element and a second resilient element each engaging the interior surface of said housing member to create a friction force associated with movement of said slider, said shutter being separate and distinct from said slider,

wherein said slider is a single-piece molded member,
wherein said shutter is a single-piece molded member,
wherein said shutter further includes a first end and a second end disposed opposite and distal the first end, the first end and the second end being disposed on an axis parallel to said interface portion,
wherein said first resilient element extends from the first end toward said second resilient element and said interface portion, and
wherein said second resilient element extends from the second end toward said first resilient element and said interface portion.

11. The electrical switch of claim 10 wherein said interface portion of said slider comprises an elongated molded portion; and wherein said elongated molded portion includes a plurality of ribs or serrations.

12. The electrical switch of claim 10 wherein said electrical switch is a dimmer switch; wherein said housing member is a removable cover; wherein said removable cover further includes a central toggle; and wherein said slider is disposed adjacent to said toggle.

13. The electrical switch of claim 10 wherein said shutter comprises a first side, a second side disposed opposite the first side, and an elongated slot disposed between the first end and the second end and extending from the first side toward the second side; and wherein the elongated slot of said shutter is substantially aligned with the elongated slot of said housing member.

14. The electrical switch of claim 13 wherein said attachment portion of said slider comprises a first resilient prong extending outwardly from said interface portion and a second resilient prong extending outwardly from said interface portion opposite and spaced from said first resilient prong.

15. The electrical switch of claim 14 wherein said shutter further comprises a mounting portion disposed on the second side; and wherein said first resilient prong and said second resilient prong extend through the elongated slot of said housing member and through the elongated slot of said shutter to removably engage said mounting portion of said shutter.

16. The electrical switch of claim 15 wherein said mounting portion includes a first edge and a second edge; wherein said first resilient prong removably engages the first edge; and wherein said second resilient prong removably engages the second edge.

17. The electrical switch of claim 13 wherein said first resilient element is a first molded spring element extending outwardly from the first side; and wherein said second resilient element is a second molded spring element extending outwardly from the first side opposite and spaced from the first molded spring element.

18. The electrical switch of claim 17 wherein said first molded spring element is disposed between the
