Abstract

A power switch including a contact configured to selectively electrically connect a line input to a load output, a switch configured to selectively control the contract, and an indicator. The contact has a closed position in which the line input is electrically connected to the load output, and an open position in which the line input is not electrically connected to the load output. The switch has an on position wherein the contact is controlled to be in the closed position, and an off position wherein the contact is controlled to be in the open position. The indicator provides a normal on status, a normal off status, and an error on status.

First claim

What is claimed is:

1. A power switch comprising:
a line input configured to receive a line voltage;
a load output configured to output the line voltage;
a contact configured to selectively electrically connect the line input to the load output, the contact having
a closed position in which the line input is electrically connected to the load output, and
an open position in which the line input is not electrically connected to the load output;

a switch configured to selectively control the contract between the open position and the closed position, the switch having
an on position wherein the contact is controlled to be in the closed position, and
an off position wherein the contact is controlled to be in the open position; and

an indicator including a line diode, a line light-emitting diode, a load diode, and a load light-emitting diode, the indicator providing
a normal on status wherein the indicator is activate when the switch is in the on position and the contact is in the closed position,
a normal off status wherein the indicator is inactive when the switch is in the off position and the contact is in the open position, and
an error on status wherein the indicator is active when the switch is in the off position and the contact is in the closed position.

2. The power switch of claim 1 , wherein the indicator indicates when a welded contact condition exists.

3. The power switch of claim 1 , wherein the indicator is electrically coupled to the switch via at least one selected from a group consisting of a male tab and a female tab.

4. The power switch of claim 1 , wherein the indicator is electrically connected to ground via at least one selected from a group consisting of a male tab and a female tab.

5. A power switch comprising:
a line input configured to receive a line voltage;
a load output configured to output the line voltage;
a contact configured to selectively electrically connect the line input to the load output, the contact having
a closed position in which the line input is electrically connected to the load output, and
an open position in which the line input is not electrically connected to the load output

a switch configured to selectively control the contract between the open position and the closed position, the switch having
an on position wherein the contact is controlled to be in the closed position, and
an off position wherein the contact is controlled to be in the open position; and

an indicator providing
a normal on status wherein the indicator is activate when the switch is in the on position and the contact is in the closed position,
a normal off status wherein the indicator is inactive when the switch is in the off position and the contact is in the open position, and
an error on status wherein the indicator is active when the switch is in the off position and the contact is in the closed position;

a housing including a rear portion and a front cover coupled to the rear portion, the indicator supported by the front cover; and
an indicator lens positioned between the indicator and the front cover.

6. The power switch of claim 5 , further comprising a gasket positioned between the indicator lens and the front cover.

7. The power switch of claim 6 , wherein the gasket is comprised of at least one selected from the group consisting of rubber and adhesive.

8. The power switch of claim 5 , wherein the indicator lens is comprised of plastic.

9. The power switch of claim 5 , wherein the indicator includes a line indicator and a load indicator.

10. The power switch of claim 9 , wherein the indicator lens includes a line indicator lens and a load indicator lens.

11. The power switch of claim 5 , wherein the front cover is a replacement cover.

12. A power switch comprising:
a line input configured to receive a line voltage;
a load output configured to output the line voltage;
a contact configured to selectively electrically connect the line input to the load output, the contact having
a closed position in which the line input is electrically connected to the load output, and
an open position in which the line input is not electrically connected to the load output;

a switch configured to selectively control the contract between the open position and the closed position, the switch having
an on position wherein the contact is controlled to be in the closed position, and
an off position wherein the contact is controlled to be in the open position; and

an indicator providing
a normal on status wherein the indicator is activate when the switch is in the on position and the contact is in the closed position,
a normal off status wherein the indicator is inactive when the switch is in the off position and the contact is in the open position, and
an error on status wherein the indicator is active when the switch is in the off position and the contact is in the closed position;

a housing; and
a mounting foot configured to secure the housing to a surface, the mounting foot including
a molding, and
an insert contained within the molding.

13. The power switch of claim 12 , wherein the molding is comprised of a plastic material.

14. The power switch of claim 12 , wherein the insert is comprised of a metal material.

15. A power switch comprising:
a line input configured to receive a line voltage;
a load output configured to output the line voltage;
a contact configured to selectively electrically connect the line input to the load output, the contact having
a closed position in which the line input is electrically connected to the load output, and
an open position in which the line input is not electrically connected to the load output

a switch configured to selectively control the contract between the open position and the closed position, the switch having
an on position wherein the contact is controlled to be in the closed position, and
an off position wherein the contact is controlled to be in the open position; and

an indicator providing
a normal on status wherein the indicator is activate when the switch is in the on position and the contact is in the closed position,
a normal off status wherein the indicator is inactive when the switch is in the off position and the contact is in the open position, and
an error on status wherein the indicator is active when the switch is in the off position and the contact is in the closed position;

a front cover including a retainer configured to captivate a fastener; and
a rear housing configured to be coupled to the front cover via the fastener.

16. The power switch of claim 15 , wherein the retainer is a retaining ring.

17. The power switch of claim 15 , wherein the retainer is integrated into the front cover.

18. The power switch of claim 15 , wherein the fastener includes a groove and a threaded portion.

19. The power switch of claim 18 , wherein the fastener is captivated at the groove.
