    Patent number: 4121073
    Abstract: An electrical switch actuatable upon the occurrence of a preselected level, includes a generally cup shaped, open ended housing which mounts therein a spaced pair of stationary contacts. The housing has two pairs of upwardly extending channels in its side walls, the two channels of the first pair aligned with the stationary contacts and the two channels of the second pair aligned with platform surfaces. An electrically conductive, flexible cruciform element is disposed in the housing with the distal end portions of two legs of the cruciform received respectively in the two channels of the first pair, and the distal end portions of the other two legs of the cruciform received respectively in the two channels of the second pair and resting on the platform surfaces. The stationary contacts may be disposed above or beneath the cruciform element for a normally open or normally closed switch as desired.
