Abstract
An engageable lockout and tagout device for aircraft pushbutton switches prevents attempts to electrically engage a corresponding control panel circuit of a system under service. The lockout and tagout device is configured to lock different pushbutton switch types present in a flight deck, including Korry switches, thereby preventing operators from actuating switches and alerting them that the switches have been disengaged.
Claims31
A pushbutton lockout clip for a circuit breaker on an aircraft panel, the circuit breaker having a pushbutton switch for opening and closing the circuit breaker in response to depression of the pushbutton switch, the lockout clip comprising:
- a. an attachment end having a retaining clamp defining a lockout protection wall extending between opposing engagement walls of the clamp, each engagement wall extending from a distal end of the clamp, the opposing engagement walls each being configured to clamp respective inner engagement surfaces to outer surfaces of the pushbutton switch or to outer surfaces of a switch frame surrounding at least a portion of the pushbutton switch, in a lockout/tagout position of the clip;
- and
- b. a spring-loaded clip end rotatably connected to the attachment end, the spring-loaded clip end configured to rotate the attachment end between a release position and the lockout/tagout position, wherein in the lockout/tagout position, the opposing engagement walls sufficiently cover the outer surfaces of the switch or the outer surfaces of the pushbutton switch to retain the pushbutton switch against depression.
