摘要： A pressure switch including: a spring blade; a ram pin having an angled bottom surface and laterally restrained in movement, where upward movement of the ram pin engages the spring blade such that the spring blade snap deflects to an engaged position, and where downward movement of the ram pin engages the spring blade such that the spring blade snap deflects to an unengaged position; a ball bearing in contact with the angled bottom surface of the ram pin; and an adjustment screw laterally restraining the ball bearing in movement, where a lateral inward movement of the adjustment screw relative to an outside surface of the pressure switch causes an upward movement of the ram pin, and where a lateral outward movement of the adjustment screw relative to the outside surface of the pressure switch causes a downward movement of the ram pin.

摘要： An assembly including: a disk spring; a plurality of normally closed contacts disposed in a plane below the disk spring; a plurality of normally open contacts disposed in a plane above the disk spring; a pivot ring supporting a lower surface of the disk spring; and an actuating pin having a shoulder in contact with an upper surface of the disk spring; where a movement of the actuating pin away from a header assembly snap deflects the disk spring to a first position to contact the plurality of normally open contacts, and a movement of the actuating pin towards the header assembly snap deflects the disk spring to a second position to contact the plurality of normally closed contacts.

摘要： A device, including: a sensor circuit that senses the state of contact impedance of a mechanical electrical switch; and a switch-off circuit that represents a sensed high impedance contact of the switch as a low or constant impedance, where the sensor circuit detects an open or closed condition of the switch by sensing a voltage across the switch passing a threshold value.

摘要： An apparatus includes a sensor excited by an input voltage adapted to provide a sensor output first voltage corresponding to a physical input excitation. A transformation circuit device provides the operational voltage to the sensor, detects the sensor output first voltage, nulls an amount of offset voltage in the sensor output first voltage, amplifies the nulled offset sensor output first voltage, and provide a noise filtered and temperature compensated output second voltage. A simulator circuit receives the compensated output second voltage and provides an output third voltage representative of a simulated bridge sensor, being absent of offset voltage, and being independent of temperature dependence and noise in the sensor.

摘要： A Micro Electro-Mechanical System (MEMS) device comprises an evaluator circuit that receives a temperature signal, where the evaluator circuit compares the received temperature signal to a lower threshold value and an upper threshold value, and where the evaluator circuit generates an evaluation signal indicating when the temperature signal is between the lower threshold value and the upper threshold value; and a loading circuit that receives the evaluation signal, where the loading circuit generates a first pre-set output signal indicating when the temperature signal is between the lower threshold value and the upper threshold value, and wherein the loading circuit generates a second pre-set output signal when the temperature signal is not between the lower threshold value and the upper threshold value, such that the MEMS device functions as a 2-wire electronic sense circuit providing both an indication state and deriving power from an external two-wire sense circuit.

摘要： An electronic temperature switch (10), comprises a measurement circuit (11) that measures temperature and generates an temperature signal corresponding to the sensed temperature; an evaluator circuit (12) that receives said temperature signal and compares said temperature signal to a lower threshold value and an upper threshold value, and generates an evaluation signal indicating when said temperature signal is between the lower temperature threshold value and an higher temperature threshold value; and a loading circuit (13) that in response to the evaluator circuit, generates a first pre-set output signal indicating when the temperature signal is between the lower threshold value and the higher threshold value, and a second pre-set output signal when the temperature signal is not between the lower threshold value and the higher threshold value.

摘要： Systems, devices, and methods including: a cable; a housing having a tapered exit hole connected to an internal volume; a tapered seal having a tapered outer surface and an inner aperture, where the inner aperture of the tapered seal receives the cable; an encapsulant disposed in the internal volume and about one or more wires of the cable; and a compression cap placed over the tapered seal and about a flange of the housing to compress the tapered seal into the tapered exit hole; where compression from the compression cap forces the encapsulant up inside the cable and around the one or more wires of the cable, and where curing of the encapsulant seals the cable from moisture incursion.
