Abstract

An improved footswitch is disclosed. The footswitch may have an adjustable length treadle to accommodate different size feet. The footswitch may also have a treadle having a slidable plate that facilitates the actuation of a side switch.

Claims (13)

1. A footswitch, comprising:

a base assembly;

a pivotable treadle mounted on said base assembly for providing a control output, said treadle having:

a base structure that is pivotably coupled to said base assembly, and

a plate receiving said base structure and that is slidably disposed along a linear path relative to said base structure so as to change a length of said treadle; and

a heel cup mounted on said base assembly separate from said treadle.

2. The footswitch of claim 1 wherein said plate is adjustable to selected positions.

3. The footswitch of claim 1 wherein said plate is slidably disposed so as to change a distance between a distal end of said plate and said heel cup.

4. A footswitch, comprising:

a base assembly;

a side switch mounted on said base assembly for providing a first control output;

a pivotable treadle mounted on said base assembly for providing a second control output, said treadle having a top surface and a plate on said top surface, said plate being slidably disposed along a linear path relative to said top surface and transverse to a longitudinal axis of said footswitch so as to facilitate actuation of said side switch by a user's foot.
