Actually just about the opposite.
Right On jim,,,,,,,A clearing contact breaks the circuit to the coil even if the pushbutton is 'maintained' - it keeps the coil de-energized.
Example of a clearing contact:
A Pressure Switch in series with the stop button in a motor control circuit,,,,,,,,,,often referred to as a "run permissive" as well.
Example of an Interposing Relay:
A relay controlled by the Pressure Switch mentioned above with one of the contacts of the relay replacing the Pressure Switch in the schematic.The interposing relay would be used most often when an additional function off the relay is needed.ie: one relay contact controls the motor and another contact from the same relay is alarming High or Low Pressure in what ever the Pressure Switch is being activated by.
The interposing relay coil could be a timer and keep the motor on line for a preset time and then would shut the motor down if the high or low pressure condition did not clear.
