The resistor bleeds off the charge of the capacitor when positive voltage is removed from the other side of the coil. Pilot wire circuits for protective relaying experience and practice 1942 1950 that a reactor and capacitor which had been con nected in series with the pilot wire insulating transformer to permit d c supervision had caused an a c transient resulting in momen tary closing of the relay contacts on.

It was originally intended to allow a single pushbutton switch on the dash of a vintage car to provide a latched function. The capacitor allows the coil of the relay to be energized until the capacitor stores a charge thus de energizing the coil.
