Pushbutton Switches

Pushbutton switches come in a variety of shapes and sizes and serve many purposes. One such switch is the BB16AH-HA, commonly found in commercial and military applications. This article will explore the application field and working principles of this particular switch.

Application Field

The BB16AH-HA is a standard size pushbutton switch, rated for up to 10 A of continuous current. The surface of the switch is made from polycarbonate and available in red, yellow, and black colors. It is sealed for dustproof and waterproof applications and is suitable for temperatures ranging from -40 to 85°C. This makes the BB16AH-HA particularly well suited for control panels located outdoors or in other harsh environments.

The smaller size and relatively low cost make the BB16AH-HA an attractive option for engineers looking for a pushbutton switch for a range of commercial and military applications. It is often seen in military vehicles, aircraft, and ships to control a range of systems, from audio and video equipment to navigation systems and communications devices.

Working Principle

The BB16AH-HA is a single contact, momentary action switch. It operates on the principle of a lever regulated by a cantilever spring. When the switch is pressed, the lever depresses into a "contact closed" position. When it is released, the lever is pushed up by the cantilever spring and returns to its original position, thus breaking the circuit and turning off the device.

The switch features a bimetallic strip heat sensor combined with the encased silver alloy contacts. This combination ensures the quicker and more reliable sparking needed for momentary action. The switch has two solder termination pins which are spaced 15.9 mm apart, so it can be easily and easily installed on circuits.

Conclusion

The BB16AH-HA is a standard sized, dustproof and waterproof, single contact, momentary action pushbutton switch. It is suitable for a wide range of military and commercial applications, such as radio and navigation systems, audio and video equipment, and communications devices. Its small size and relatively low cost make it an attractive option for engineers seeking a reliable switch for their projects.
