ASQM16438 snap-action, limit switches are low cost switches that provide reliable service in a wide range of applications. They are often used to sense the presence or absence of an object, or to detect the movement of an object within a given range. The switch can be configured to open or close upon actuation in one direction or bi-directionally, and it can be used in simple push-pull switching applications.

Design

ASQM16438 snap-action, limit switches feature a robust plastic housing with a UL 94V-0 flammability rating. The housing is designed to provide excellent durability and moisture protection. An adjustable actuator is mounted in a hole at the top of the housing, protected from dust, dirt and other environmental contaminants. The actuator also helps to stabilize the contacts for consistent performance over time. The external features of the switch include a mounting tab for easy installation and a marking strip for identification. The connection terminals are stainless steel backed for secure contact and are pre-stressed to require a minimum amount of force for reliable operation.

Operation

ASQM16438 snap-action, limit switches are powered by an external voltage source. When the external voltage is applied to the switch, the internal spring-loaded actuator is activated. The actuator then moves up and down, opening and closing the switch contacts. When the contacts are open, the switch remains in its reset state; when the contacts are closed, the switch is triggered. The switch will remain in its triggered state until the external voltage source is removed and the actuator resets.

Applications

ASQM16438 snap-action, limit switches are used in a variety of applications, including machine control, flow meter monitoring, light control, safety systems, door and window sensors, vending machines, and temperature control. The switches are suitable for low to medium duty applications and are well-suited for use in harsh environments due to their robust construction.

Conclusion

ASQM16438 snap-action, limit switches are low cost, reliable and durable switches that are suitable for a variety of applications. The switches feature a robust construction, adjustable actuator, and pre-stressed connection terminals for reliable operation. They are suitable for use in a variety of low to medium duty applications, including machine control, flow meter monitoring, light control, safety systems, door and window sensors, vending machines, and temperature control.
