ABD301N-B

Pushbutton Switches

The ABD301N-B is an IP67, 19mm, pushbutton switch designed for use on equipment where a waterproof and dustproof operating switch is needed to select or operate an electrical circuit. This switch is particularly suitable for submerged applications, and is ideal for use in water, oceans, showers, and other harsh applications. The ABD301N-B’s construction consists of a polyester based polyurethane body with a zinc plated steel insert for corrosion resistance in hostile environments. The polyurethane material and zinc insert combination ensures robust construction and durability, making the ABD301N-B a reliable solution in extreme and hazardous environmental conditions.

Application Field

The ABD301N-B is most suitable for underwater, marine and corrosive environments. It is suitable for applications that require operation underwater such as operating pool filters, controlling water jets, and controlling other water systems. In addition to underwater applications, it is also suitable for medical, gas and oil, and automotive applications. In these applications, the switch is primarily used to operate electronic devices, select operational mode, or as a momentary switch when an on-off signal is required.

Working Principle

The ABD301N-B is designed with a three-piece switch design that allows for varying electrical functionality. This switch has a single pole (SP) configuration and is rated for 10A@120V AC, and 2A@250V AC. This switch is momentary, meaning it requires a positive forward push margin of 20N to activate, and requires 0.2N for return to off position. Additionally, the ABD301N-B features a built-in glass-filled nylon collar that helps to reduce RF interference and ghosting.

The steel brass insert on the ABD301N-B is designed with a number of anti-turnout technology to prevent rotation, deterioration, and ingress of contaminants after installation. This technology includes an iron guard and a locking mechanism system, ensuring the switch remains in place regardless of mechanical shock and vibration that may occur. Additionally, the ABD301N-B is IP67 rated, making it dustproof and waterproof to 1 meter.

Conclusion

The ABD301N-B is a 19mm, pushbutton switch designed for extreme and hazardous operating environments. It has a single pole configuration and is rated for 10A@120V AC, and 2A@250V AC. This switch features an iron guard and locking mechanism to help prevent tampering, and is IP67 rated for dustproof and waterproof operation to 1 meter. It is suitable for underwater, marine, medical, gas and oil, and automotive applications.
