These bell push buttons can be used with any make of wired doorbell that is powered by a transformer operating at 8 volts A/C. They should not be use with battery operated chimes or Wired to Wirefree Extenders, since in both cases the light will drain batteries. The term, Surface Mount,, means that the movement of the bell push button is in front the front plate, so there is only the need for a small hole behind the plate to accomodate the bell wire.
