In the distal extension RPD support is derived from both the residual ridge and abutment teeth. The variation in consistency providing this support allows some rotational movements of the free-end base towards the soft tissues. The GHQRSPEL circuit breakers contains both a solenoid operated remote switching circuit and a manually operated thermal-magnetic circuit breaker.
