Introduction

A pushbutton switch is a type of actuator used for mechanical operation of a system. Examples of applications for these switches include home appliances, telecommunication devices, and access control systems. The 8646ABUL is a pushbutton switch manufactured by Allen-Bradley, the well-known brand of industrial control technology from Rockwell Automation.

8646ABUL Application Field

The 8646ABUL is a pushbutton switch with a maximum rated current of 2 Amps. The switch is also offered with a lockable actuator, making it suitable for industrial safety applications where secure operation is essential. This switch features a stainless steel actuator, cooper contacts and an aluminum roller bracket, ensuring it is reliable and safe in all applications. The 8646ABUL is a single-pole, momentary action switch and is commonly used in applications where a single, simple boost of power is required to activate a device. This switch can be found in applications such as HVAC controls, emergency stop systems, emergency door opening systems, and remote parallel reset controls.

8646ABUL Working Principle

The 8646ABUL operates on a simple mechanical mechanism. When the actuator is pressed down it causes the internal contacts to be closed, which allows current to pass through the switch and to the load. When the actuator is released, the internal contacts open, disconnecting the power to the load. The 8646ABUL is designed for minimum contact bounce and maximum contact reliability. The contacts are made of cooper which provides a good electrical connection with low contact resistance. The contacts are also designed with a \'distributed wipe\' system. This is a method of matching the contact material geometry to the internal switch mechanism in order to reduce electrical contact noise and maintain long-term reliability.The 8646ABUL is rated for up to 2 Amps of current, making it suitable for most low-power applications. The switch also features an IP67-rated enclosure, which means it is dust-proof and water-resistant.

Conclusion

The 8646ABUL pushbutton switch is a reliable, economical switch intended for use in applications where a momentary boost of power is required. The 8646ABUL features an IP67-rated enclosure, stainless steel actuator, and cooper contacts, making it suitable for a wide range of applications. It is perfect for applications such as HVAC controls, emergency stop systems, emergency door opening systems, and remote parallel reset controls.
