831607B6.A

Snap action, limit switches are versatile components used in almost every form of automation, providing vital feedback or control functions. There are a couple of different types of snap action limit switches, one of the most common being 831607 B6.A.

This particular type of switch is characterised by its snap action triggering, augmented by a single pole, double throw contact arrangement, providing a normally closed function. Therefore it is only when the switch is actuated that the contacts are opened. It is this action that is most commonly associated with the 831607 B6.A and it is the precise snapping of the contacts that gives the switch its name.

In terms of its actual construction, it is a plastic housing, typically with a roller lever actuator, but, depending on the application, there are other levers available. As indicated earlier, the component has a single pole, double throw mechanism, meaning that it has one (single pole) moving contact that is toggled between two (double throw) fixed contacts. The other part of the component comprises of sealed pushbutton terminals connected to a NEMA 4 rated housing. The seals are manufactured from Neoprene, ensuring that the switch will operate in a range of environments.

In terms of application fields, the 831607 B6.A has uses in many areas, such as in machinery and equipment, including packing machinery, gates and doors, conveyors and general automation. As an example of typical applications, the 831607 B6.A could be attached to a machine\'s door. The switch is wired in series with the machine\'s power supply, meaning that when the door is opened, the contacts within the switch open, so the current is broken and the machine stops running.

As for its operation principle, it is really very simple. When the actuator is manually actuated, the roller lever pushes the contact arm away from the stationary contact, thus opening the contacts. This action occurs very quickly and is why it is termed a snap action switch. When the actuator is released, the natural spring action of the component contacts the stationary contact, thus restoring the current.

In conclusion, the 831607 B6.A snap action limit switch is a reliable, versatile and easy to set up component. It offers a wide range of applications from general automation to more specialized environments. It is used to reliably provide an open circuit when actuated and then restoring the closed circuit when the actuator is released. It is designed with a rugged and sealed construction for environmental protection and can also be fitted with a variety of lever types to suit specific applications.
