A snap action, limit switch is a switch which is either activated or deactivated when some physical or electrical property reaches or passes beyond a given threshold of variation. Snap action, limit switches are usually installed to monitor system performance and detect irregularities. The DA3C-D1AA is a type of snap action, limit switch which offers varied switch application fields and working principles.

Switch Application Fields

The DA3C-D1AA can be used in a wide variety of different application fields such as position monitoring, speed monitoring, replicating a mechanical lever movement and operation of switching components. The features of this snap action, limit switch are suitable for use in many industrial and automotive applications, as well as consumer electronics and information technology.

Working Principle

The working principle of the DA3C-D1AA is based on two main parts. The first is the switch lever which is pivoted in a cam-lever type joint. The second part is the actuator which is a driver that impels the movement of the lever. The actuator can be any type of controller or system, such as a servo motor, stepper motor, electro-mechanical device or even a human hand. When the actuator triggers the appropriate action, the switch lever is then triggered according to its design.

The DA3C-D1AA is built with a switching element, usually a reed contact, which is activated when the levers motion impels movement of the switch element. The lever and switching element are spring-loaded and always return to the same valve position in readiness for the next function. When a set point that has already been set is reached or exceeded, the switch element will activate or deactivate its function.

The DA3C-D1AA snap action, limit switch is a robust and reliable switch device with proven long-term performance. The versatile design offers application fields from short travel position monitoring, over speed monitoring and delivery of electrical signals up to power connections/switching elements between a controller and a load.
