  • Publication number: 20150102875
    Abstract: The disclosure refers to a switch which is suitable to protect an electric circuit against overloading. The switch generally consists of a triggering assembly as well as of an interrupting assembly, wherein said triggering assembly comprises and induction unit, a thermic interrupter and an actuating needle. The induction unit comprises a coil with a yoke intended to displace the actuating needle towards the triggering assembly, when the short circuit occurs. Said thermic interrupter comprises a bimetallic membrane, which is mechanically interconnected with the actuating needle and is in the case of excess current and generating of heat displaced towards the interrupting assembly. In order to provide such switch, which could moreover enable protection against transient voltage, e.g. due to thunder bolt, such switch is furnished with a varistor, which is located within the triggering assembly in a heat-conductive relationship with said thermic interrupter.

  • Patent number: 5932856
    Abstract: A power switch for use with a personal locator beacon (PLB), or an emergency position indicating radio beacon (EPIRB), that prevents accidental activation of the beacon to prevent false alarm transmission of emergency signals. The personal locator beacon includes electronic circuitry housed in a portable hand-held housing that includes a fail safe power switch which has a lever arm that is selectively movable between first and second offset recessed cavities formed in the housing. The lever arm is rotatable about a shaft between an "off" position wherein the lever arm is received within the first cavity, and an "on" position wherein said lever arm is received within the second cavity. An edge portion formed by the offset cavities stops the lever arm from rotating from the first position to the second position unless the lever arm is manually moved laterally along the shaft to clear the edge portion.

  • Patent number: 4371762
    Abstract: A contactless pressure switch 10 sensitive to fluid pressure rates of change includes a housing 36 and a diaphragm 42 secured in the housing defining first and second chambers. Ports 48, 50 are included in the first and second chambers to vent the chambers. A magnet 52 is secured to the diaphragm and a switching module 54 is secured to the housing within one of the first or second chambers at a position spaced from the diaphragm. A biasing magnet 53 is mounted with the module to provide symmetrical switching by the module. The other of the first or second chambers is coupled to a sensing tube 28 such that upon a pulse or rate change of pressure being introduced in the other of first and second chambers, the diaphragm is deflected. This moves the magnet 52 toward the module actuating it to switch the module and actuate a desired circuit. In an alternative embodiment, the position of the module may be varied relative to the diaphragm to vary the sensitivity of the switch.

  • Patent number: 4103121
    Abstract: Main contact and interrupter contact operating rods of opposed current interrupters are sequentially moved by a spring loaded operating mechanism to open the main contacts and interrupting contacts of the interrupter switches. Rotation of an input shaft trips a first overcenter toggle linkage by the engagement of a cam on a drive lever operably connected to the shaft. Tripping of the first overcenter toggle linkage allows the springs to rapidly move a main rod arm assembly connected to the main contact operating rods to open the main contacts. Rotation of the main rod arm assembly trips a second overcenter toggle linkage connected to a fast rod arm assembly permitting springs to rotate the fast rod arm assembly connected to the interrupter contact rods to open the interrupting contacts in sequence. Continued rotation of the shaft in the same direction causes abutments on the drive lever to engage the main rod arm assembly and the fast rod arm assembly to recock the mechanism for subsequent operation.
