ABV1215503R

Snap Action, Limit Switches

The ABV1215503R (ABVXL) is a snap action, limit switch manufactured by SELMA Voltage Regulators. It is primarily used in controlling, monitoring and safety applications in industrial, commercial and automotive applications. The ABVXL is capable of switching up to 4A 250V AC or DC and comes in various models for varying operating environments, including shock and vibration-resistant models. The ABVXL is also resistant to temperature extremes, water and dust.

The operating principle for the ABVXL switch involves a contact that is held in either the opened or closed position by a spring. The spring holds the contact in the opposite of the state of the switch until the voltage or current that travels through the switch is increased enough to cause the contact to move. This movement is referred to as “snap action” and allows the switch to switch rapidly and reliably.

The ABVXL switch is usually wired such that a low voltage or current can open or close the circuit when the contact is moved. The low voltage or current can come from a variety of sources including a manual controller, a thermocouple, or a temperature sensor. Most switch designs use a latching mechanism to keep the switch in whichever position it is set until it is released. This is accomplished by using a single wire or a double wire system to open and close the circuit.

The ABVXL switch is ideal for applications where speedy switching is desired, such as in motor controllers, control systems, safety systems, and industrial robotics. Its “snap action” makes it well suited for quick action applications where a regular contact would not be fast enough. The switch is also suitable for slow action applications, such as limit switches, speed sensors and hydraulic switches, as the snap action does not interfere with the slower operating speeds.

The ABVXL switch is available in a range of sizes and configurations. The switch is offered in both normally open and normally closed configurations and is also available as a dual-action switch with multiple contacts. For a given application, the selection of the switch depends on the particular requirements of the application and on the available space. The ABVXL switch is UL and CSA approved and meets European and American safety standards.

The ABVXL switch is a reliable and versatile switch designed for a wide range of industrial, commercial and automotive applications. Its snap-action design makes it well suited for switching fast-acting circuits and its temperature and vibration-resistant capabilities make it suitable for robust applications. Its UL and CSA approvals ensure that it meets required safety standards. Furthermore, its range of sizes and configurations make it an ideal choice for a variety of applications.
