Snap Action, Limit Switches are widely used in fields of safety, industrial automation, and home appliances, to accurately detect the motion or position of a mechanism in a specific area with limit switches or to timely execute an action when the mechanism moves to a certain point. T5009-021F1N, as one of the representatives, has precise and excellent performance.

T5009-021F1N belongs to the Type 21 Miniature, compact, snap action limit switch products. It provides superior performance over other common types of switches. This model features two independent circuits- Normally Closed and Normally Open-built into a single device; there is an additional terminal with a common shaft. This ensures reliable, low cost and highly accurate switching. In addition, its elegant design plus small size and light weight makes it easy to place or rotate inside narrow or limited areas.

In terms of application field, T5009-021F1N is mainly used for object position detection, object size detection, object level measurement and object conveyor control. It has been widely used in safety switches, warning systems, motor starting, position sensing, limit sensing, overload/short circuit protection, conveyor speed control and counting operation, etc. Moreover, this product has wide application in light industry, home appliances and other areas.

The working principle of T5009-021F1N is based on a bimetallic strip reaction to movement. When the angular displacement of the operating armanglele is small, one part of the bimetallic strip will be heated and the other part cooled, thus causing the strip to bend and the contact of the switch operated. The components of the switch include a stainless steel actuating arm, a bimetal strip, a pair of dielectric contacts and a hole plate. The actuator is pivoted at its center by the hole plate and is pre-biased with a spring. As the actuator moves, the leading contact point on the bimetal strip bends, allowing the arm to move freely until the contacts make or break. The pre-setting of the switch is accomplished by adjusting the actuator arm and depressing it against the bimetal strip until the operating point is attained. The resetting of the switch is thus easily achieved.

In conclusion, T5009-021F1N is representative of Snap Action, Limit Switches due to its precision and excellent performance. It is widely used in fields such as safety, industrial automation, and home appliances for object position detection, object size detection, object level measurement and object conveyor control. The working principle of this product depends on bimetallic strip reaction to movement and the components includes a stainless steel actuating arm, a bimetal strip, a pair of dielectric contacts and a hole plate.
