Snap action switches limit the range of motion of a control, such as a knob or lever, to a certain desired angular position. They are durable and usually immune to mechanical abuse. Snap action switches are found in a variety of electronic applications, from automotive to industrial, home and commercial applications. ER6022-021MEL is a general purpose snap-action limit switch that is reliable and easy to install. By understanding its application field and working principle, users can maximize its usage and benefits.

Application Field of ER6022-021MEL

The ER6022-021MEL is a low-cost, highly reliable and easy to install snap-action, limit switch. It is suitable for a variety of industrial, automotive, home and commercial applications. It is commonly used in security and fire alarm systems, elevators, motorcycles, medical equipment, stage and studio light systems, and such. It has long-life performance with working current and voltage ratings of 2A and 250VAC, respectively. The switch features a reliable, fast-acting snap action contact, and is available in a wide range of different models with different actuating forces and TUV approved.

Working Principle of ER6022-021MEL

The ER6022-021MEL works on the principle of snap-action, limit switches. In a snap-action switch, when the actuating plunger is deflected to its actuation position, the spring contact is forced to move from its resting position to its active position. This causes the switch to “snap”. The instantaneous contact closure of the switch is called “snap action”. When the plunger is released, the spring contact is returned to its resting position.

The snap-action limit switch works in a similar way. When the actuator is displaced more than the actuation point, the contact will “snap” to the contact position. This will cause the switch to turn on or off, depending on the switch configuration. The spring contact will stay in the contact position until the plunger is deflected back to the actuation point. When it is deflected back, the switch will automatically reset.

Conclusion

The ER6022-021MEL is a reliable, durable, and economical snap-action limit switch that is suitable for many applications. By understanding its application field and working principle, users can maximize its usage and benefits. This switch is easy to install, has a long life, and is immune to mechanical abuse, making it an ideal choice for any residential, commercial, and industrial electronics applications.
