A miniature aircraft type circuit breaker (10') has a threaded mounting bushing (18) in which a push button (20) is slidably received. Push button (20) is coupled to a movable contact arm (24) to move a movable electrical contact (26) into and out of engagement with a stationary electrical contact (28). A flexible fluid splash barrier sleeve (32) is telescopically received on a reduced diameter portion (34) of push button (20) above a white indicator portion (30) of the push button and has a lower distal end portion (36) which engages an annular top surface (38) of the bushing when push button (20) is depressed to bring the electrical contacts into engagement. Adhesive material may be used to affix the barrier sleeve to the reduced diameter portion (34) which optionally can have a roughened surface to enhance adhesion.
