Abstract
An foot pedal switch assembly including a panel for mounting a foot pedal and a switching mechanism, wherein the panel includes a debris fence surrounding the switching mechanism and the pedal has a cap structure molded in the bottom to telescopically engage around the debris fence forming a substantially continuous barrier to the entry of dust and debris into the switching mechanism.
Claims10
A foot pedal switch assembly comprising:
- a switching mechanism;
- a panel having an opening extending therethrough in which said switching mechanism is disposed, wherein the switching mechanism is accessible through the opening;
- an upstanding rigid debris fence fixedly attached to and rising from the panel and surrounding the opening on at least three sides for fending loose debris from said opening;
- a pedal movably mounted on the panel and disposed over the switching mechanism so that the pedal selectively actuates and de-actuates the switching mechanism;
- and
- a cap attached to and extending downwardly from the bottom of the pedal and positioned to telescopically interfit with the debris fence.

A foot pedal switch assembly comprising:
- a panel section of stiff plastic material having an opening extending therethrough;
- a switching mechanism disposed within said opening such that the mechanism is accessible through said opening;
- an upstanding shallow debris fence of stiff plastic material integrally fixedly joined to said panel section for fending loose debris from said opening and having a pair of elongate side-protecting courses extending adjacent opposite sides of said opening and an interconnecting course joining adjacent ends of said side-protecting courses beyond one end of the opening;
- a foot pedal of stiff plastic material hingedly connected to said panel section at a position located beyond the end of said opening opposite the said one end of the opening;
- and
- an elongate skirt integrally joined to an underside of said foot pedal and descending downwardly therefrom, extending in courses closely adjacent said side protecting and interconnecting courses of said debris fence.
