Snap Action, Limit Switches are products from a class of electromechanical devices that feature a sensing element that responds to environmental parameters, most commonly being physical contact with the object and work by opening and closing an electrical contact. The WS0850101F050WA is one such product and is used in a diverse range of applications. This article looks at the WS0850101F050WA and explains its application field and working principle.

Application Field of the WS0850101F050WA

The WS0850101F050WA is a micro switch actuator which features a single pole double throw (SPDT) contact arrangement. It is designed to be used in low to mid range automation applications, such as where control limits, reset or reversing functions are required. Examples of this include controlling fans, motors, and pumps, as well as automated process control systems.

It is also suitable for applications that require manual operation and are exposed to a wet or corrosive environment. Examples of this include controlling valves, louvers, small doors or windows, as well as machine tool doors. It is also used in machine tool cages and forestry machinery.

Additional uses include light machine tools, small scale transformers, roller door motors, small heat exchangers and industrial exhaust systems.

Working Principle of the WS0850101F050WA

The working principle of the WS0850101F050WA is based on the use of a spring-loaded plunger which triggers a switching mechanism when it is mechanically actuated. The mechanical action causes a momentary switch-over in the SPDT contact, which is then held in the ‘on’ position by a magnetic field generated by the plunger. The magnetic field is usually between 0.25 and 0.5 millimetres so it is not visible.

The WS0850101F050WA is designed for operation in a normally open or normally closed circuit, with a few models having an intermediate or additional mechanical feature. The mechansim has a contact force of 8.5 Newtons, a contact rating of 10 Amps and a switching capacity of 20 Watts.

The actuator comprises a body housing with a switch lever and a plunger. The actuator is energized by pushing the plunger into the body housing, triggering the switching mechanism, and then releasing the plunger. The plunger will then return to its original rest position using the powered return spring.

The operating temperature range for the WS0850101F050WA is between -20 and +50 Celsius, making it an ideal switch for a variety of applications. The product is also RoHS compliant.

Conclusion

In conclusion, the WS0850101F050WA is a Snap Action, Limit Switch that is used in a wide range of applications, from controlling fans and motors, to Industrial exhaust systems. It is designed for operation in a normally open or normally closed circuit, with a few models having an intermediate or additional mechanical feature. It has a contact force of 8.5 Newtons and a contact rating of 10 Amps with a temperature range between -20 and +50 Celsius. It is a product designed for low to mid range automation applications and is RoHS compliant.
