ABSTRACT:
An electrical sequencing relay has an elongated bimetal member with a transverse curvature opposing temperature warp and maintaining the member straight in a longitudinal direction until longitudinal temperature warp forces exceeds the retaining forces of the transverse curvature. A slidable insulative operator is engaged by a free end of the bimetal member to operate an electrical switch when the bimetal member abruptly changes its longitudinal curvature.
