ABSTRACT:
Electrical relay apparatus in which a contact spring (35) is bowed rather than angularly flexed by the armature (16) to bring the contacts (28, 38, 34, 39) into or out of engagement. A first contact (38) is mounted at the crown of a slightly bowed spring (35) fixedly mounted at one end. The contact (38) is mounted at near the midpoint of the spring (35) spaced apart from a second, fixed contact (28) and the contacts (28, 38) are brought into engagement by the further bowing of the spring (35) by an armature (16) acting along the spring axis in the direction of its fixed end. A second contact (39) mounted on the underside of the spring (35) may be brought out of engagement with a second fixed contact (34) by the further bowing of the spring (35) for a break-before-make mode of operation.
