Abstract
A relay and a method for indicating a relay failure may be provided, whereby the relay comprises a switch assembly capable of providing a trigger signal based on a switching status; an energisation element capable of energisation to affect the switch assembly; and a light indication for indicating a switching status of the switch assembly.
Claims19
A relay comprising:
- a switch assembly configured to provide a trigger signal based on a switching status;
- an energization element configured to energize the switch assembly to change a switching status of the switch assembly;
- and
- a light indication configured to indicate the switching status of the switch assembly, the light indication including an optical filter, the optical filter controlled by the switch assembly to alter the light indication based on the switching status;
- wherein the energization element is coupled to the switch assembly and the switch assembly is coupled to the optical filter such that energization of the energization element activating the switch assembly causes the optical filter to move automatically.

A method for indicating a relay failure, the method comprising:
- providing a switch assembly for transmitting a trigger signal based on a switching status;
- providing an energization element for affecting the switch assembly to change a switching status of the switch assembly;
- and
- indicating the switching status of the switch assembly using a light indication, wherein indicating the switching status includes controlling, by the switch assembly based on energization of the energization element to change a state of the switch assembly, an optical filter coupled to the switch assembly to automatically move to alter the light indication based on the switching status.
