A reed switch including a cylindrical enclosure with two ends, a first blade and a second blade is disclosed. The first blade has a first lead, a first web, and a first contact, and the first web is bent at a first angle as compared to the first lead. The second blade has a second lead, a second web, and a second contact, and the second web is bent at a second angle as compared to the second lead. The first contact is disposed adjacent to the second contact with a gap between them.

The present disclosure relates to a coolant level sensor device for application in vehicles, comprising three interoperable component parts: a housing component, an interchangeable cartridge assembly, and a resistor pigtail. The housing component may be configured to permanently and/or semi-permanently reside within the engine cooling system such that the housing component may receive the interchangeable cartridge assembly selectively connected with the resistor pigtail. The interchangeable cartridge assembly may comprise a reed switch that may be replaceable when damaged. Further, the interchangeable cartridge mechanism may be configured to connect with the resistor pigtail, which may include at least one resistor, such that the at least one resistor may be removed from close proximity to the high temperatures generated by the engine, thus increasing the life of the resistor components. This three part configuration may allow for the easy replacement of elements of the coolant level sensor prone to failure, without the need to replace functioning components.

A processing system includes a master control module, an order module, a magnetic sensitive element sorting module, a pin processing module, a lead processing module, a pin lead welding module, a casing module and a glue injecting module, wherein the magnetic sensitive element sorting module is configured to grade and screen magnetic sensitive elements, the pin processing module is configured to process pins of magnetic sensitive elements, the lead processing module is configured to process wires into leads, the pin lead welding module is configured to weld leads on the pins of magnetic sensitive elements to form sensing elements, the casing module is configured to sleeve the sensing elements into the accommodating cavity of a shell, and the glue injecting module is configured to inject glue into the accommodating cavity of the shell to encapsulate the sensing elements and form magnetic switch sensors.

A key preloading structure including a base, a set of switches and a set of keys is provided. The set of switches is arranged on the base. The set of keys has a rotating shaft and two actuators. The rotating shaft is assembled on the base. One end of each actuator is fixedly connected to the rotating shaft, and another end is disposed on a switch of the set of switches. Each of the two actuators preloads the set of switches with a force less than a triggering force for starting the set of switches.

A key preloading structure including a base, a set of switches and a set of keys is provided. The set of switches is arranged on the base. The set of keys has a rotating shaft and two extended elastomers. The rotating shaft is assembled on the base. One end of each extended elastomer is fixedly connected to the rotating shaft, and another end is disposed on the set of switches. Each of the two extended elastomers preloads the set of switches with a gravity less than a triggering force for starting the set of switches.
