Claims26
A switch stand comprising:
- a base;
- a housing resting on said base;
- a shaft mounted for rotational movement within said housing;
- a first cradle upstanding from said base;
- a second cradle upstanding from said base;
- and
- a lever arm affixed to said shaft, said lever arm including a handle defining a closed area, said lever arm and handle movable arcuately between a first position contacting said first cradle and a second position contacting said second cradle, said first position and said second position separated by an angle 120 degrees or less.
