    摘要: A safety control circuit for an electric combination cleaner includes an on-delay relay (18) operatively coupled with the motor start relay (16) together with an off-delay relay (40) operatively coupled with the start switch (30) and the pump motor relay to provide automatic predetermined time delays upon start-up and shutdown to avoid overheating and thus damage to the equipment.
