Abstract
A system for selecting coil voltage in an electrical device comprises a housing and a coil in the housing having a plurality of windings. Each winding has a pair of pins. A slider supports a plurality of moveable contacts and is moveably mounted in the housing proximate the coil so that the plurality of moveable contacts selectively make or break electrical contact between the winding pins to select coil voltage.

A system for selecting coil voltage in an electrical device comprising:
- a housing;
- a coil in the housing having a plurality of windings, with each winding having a pair of pins;
- a plurality of moveable contacts;
- and
- a slider supporting the plurality of moveable contacts and being moveably mounted in the housing proximate the coil so that the plurality of moveable contacts selectively make or break electrical contact between the winding pins to select coil voltage, wherein the slider includes a plurality of ribs and the housing includes a plurality of slots so that if the slider is in an unlocked position the ribs are aligned with the slots and if the slider is in a locked position the ribs are not aligned with the slots and are engageable with the housing to selectively lock the coil in the housing.
