    50 Hz Stack dryer door-switch relay A Door Switch Relay is needed for IEC approval for single-load and stack 50 cycle dryers. On 60 cycle and mechanical timer dryers the centrifugal switch handles the latching means for maintaining power to the motor after the push to start switch has been pressed and released. Due to the fact that this centrifugal switch holds until the motor rpm drops below a certain level, this has been deemed unacceptable per current IEC testing.
