Abstract
An electrical device (20), in particular an energy regulator or infinite switch, comprises a body portion (22) with one or more electrical elements (33, D, B, C, 47) mounted thereto. The body portion (22) and the electrical element(s) (33, D, B, C, 47) mounted thereto define an assembly having a minimum dimension which is termed the “thickness” of the assembly. At least one terminal (25, 57, 58, 59, 60, 61, 63) is also mounted to the body portion. The terminal has a mounting portion (27) and a contact portion (26) with the mounting portion (27) extending transversely to the thickness dimension to thereby result in a low-profile electrical device.
Claims22
An energy regulator for an appliance comprising:
- a body portion;
- one or more electrical elements mounted to the body portion, the body portion and at least one of said electrical elements defining an assembly having length, breadth, and thickness dimensions, the thickness dimension being the minimum external dimension of the assembly;
- a plurality of electrical terminals mounted in the body portion, at least one of said electrical terminals having a mounting portion and a contact portion, the mounting portion extending transversely to the direction of said thickness dimension and being received in a recess formed in a side of the body portion, which side is substantially parallel to the thickness dimension, the mounting portion being adapted for sliding assembly into the recess;
- wherein said contact portion extends substantially parallel to said thickness dimension and does not extend substantially beyond said thickness dimension.
An energy regulator for an appliance comprising:
- a body portion, wherein said body portion is substantially planar;
- one or more electrical elements mounted to one face of said body portion;
- a rotary control actuator mounted to another face of said body portion, wherein the longitudinal axis of said rotary actuator extends substantially transversely to the plane of said body portion;
- a plurality of electrical terminals mounted in the body portion free from mechanical contact with make/break contacts, each of said electrical terminals having a mounting portion and a contact portion, the mounting portion extending substantially transversely to the longitudinal axis of said rotary actuator and being received in a recess formed in a side of the body portion, said side being substantially parallel to the longitudinal axis of said rotary actuator, said mounting portion being adapted for slidable receipt into said recess;
- said contact portion extending substantially parallel to the longitudinal axis of said rotary actuator;
- and
- said one or more electrical element and said plurality of terminals extending from the same face of said body portion.
A method for fabricating an energy regulator for an appliance, said method comprising:
- providing an assembly having length, breadth, and thickness dimensions, the thickness dimension being the minimum external dimension of said assembly, said assembly including one or more electrical elements mounted to a body portion, said body portion including a plurality of recesses formed in at least one side thereof, said side being substantially parallel to the thickness dimension;
- providing a plurality of electrical terminals, each of said terminals including a contact portion and a mounting portion;
- selectively inserting each of said terminals into each of said recesses, said mounting portion extending transversely to the thickness dimension, said contact portion being substantially parallel to the thickness dimension and not extending beyond the thickness dimension.
