That’s the point of having Capacitive Discharge Units.
When the control unit is pressed the C.D.U. emits a single pulse to activate the twin-coil remote switch motor(s).
No matter how long you keep the control unit depressed it only send out the single pulse and does not allow for continuous power that can damage these type of remote switch motors.
This can be a necessity when having guest(s) unfamiliar with twin-coil remote switch motors or children that just like to push buttons continuously from damaging the units.
Also, because it is a capacitor the amperage generated through the discharge pulse has the power to move two PECO Side Mounted Switch Motors simultaneously.
Before installing the C.D.U.s I could activate two Atlas Remote Switch Machines from the same control unit but not two PECO Side Mounted Switch Motors.
By using the C.D.U.s a single control unit will now activate two PECO Side Mounted Switch Motors simultaneously.
