Pushbutton Switches - BB26AP-HA Application Field and Working Principle

Pushbutton switches are commonly used in a wide range of electrical and electronic applications. From the simplest of low-voltage applications (e.g. turning a lamp on and off) to more complex and sophisticated controls, pushbuttons provide the means to control a number of different functions. One type of pushbutton switch which is increasingly becoming popular in commercial and industrial settings is the BB26AP-HA. This article examines the application field and working principle of this switch, in order to understand its advantages over other types of buttons and switches.

The BB26AP-HA is an illuminated, robust pushbutton switch. It is available in a range of cap and LED colours, with a range of contact form variations, voltage ratings and actuator sizes. It is suitable for many applications, including construction equipment, machine tools, lighting controls as well as in medical and commercial equipment. Its robust construction and long life mean that it is also suitable for use in applications where high levels of vibration or harsh environments may be encountered.

The BB26AP-HA features a finger guard plate to protect against accidental finger contact with the switch contacts, and the contacts are sealed to IP67, making the switch suitable for use in wet environments. The switch is easy to install, reducing maintenance time and costs. It has a wide operating temperature and can be used in temperatures from -25C to +85C for extended periods.

The BB26AP-HA pushbutton switch operates on the ‘push-in, pull-out’ principle. When the actuator is pushed in, the electrical contacts will connect, completing a circuit. Once the actuator is pulled out, the circuit is opened. The switch is normally open when the actuator is out and closed when the actuator is in. The operating force required to operate the switch is determined by the contact form chosen. A wide range of contact forms is available, including single throw, double throw, momentary, long life, and long lasting.

The BB26AP-HA pushbutton switch has a number of advantages over other types of switches. It is waterproof and vibration-resistant, so it is suitable for use in rugged and harsh environments. The long actuation life means that it provides reliable operation in applications where frequent use is required. Finally, its compact size and wide range of cap and LED colours mean that it can be used with great flexibility in applications where aesthetics are key.

In conclusion, the BB26AP-HA is a robust, high-quality switch which is suitable for a wide range of applications. Its waterproof and vibration-resistant construction, long actuation life and wide range of contact forms make it an ideal choice for installations which require switch reliability and flexibility. Its compact size and range of cap and LED colour choices make it aesthetically pleasing, making it suitable for even the most demanding of installations.
