We have two of the old type of horn relay switches which we would like modified, to bring them up to present standard. The modifications involves an extra winding being fitted on one of the bobbins; the object being to produce a loud note when the push-button is pressed in such a manner as to make simultaneous contact with both "loud" and "soft" terminals. Will you please arrange for the return and modification of these units. Order No. 54317. Received HS{Lord Ernest Hives - Chair}/Wst. | ||
