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.
Claims10
An electromechanical device having a selectable coil voltage comprising:
- a housing;
- a coil in the housing having first and second windings, each winding having a pair of pins;
- an electromagnet associated with the coil in the housing for driving an actuator responsive to energization of the coil;
- a pair of moveable contacts;
- and
- a slider supporting the pair of moveable contacts and being moveably mounted to the coil so that the plurality of moveable contacts selectively make or break electrical contact between the winding pins to select coil voltage.
