Beschreibung
Zusammenfassung:	A brake actuator having a switch device mounted to an actuator housing with a spring member partially surrounding an actuator rod and adapt ed to contact a large diameter section of the actuator rod when brake wear caus es the actuator rod to travel to a service limit position. In normal operation the spring member is separated from a small diameter section of the actuator rod . The switch device is mounted to a first end of the spring member having firs t and second electrical contacts which extend and electrically contact a conductio n plate attached to a second end of the spring member as long as the brake actuator rod has not traveled to the service limit.
