Pushbutton Switches

Pushbutton switches are devices used to control electric circuits in a variety of applications. They are widely used in home appliances, consumer products and industrial control circuits, such as automotive, medical, and military equipment. One such pushbutton switch is the A3PA-90A11-28, which is a one-position, small-size, momentary action, button-style pushbutton switch. It is used in home appliances, consumer products, automotive and office automation. The A3PA-90A11-28 has a compact size of 28mm in length and 18mm in width. It is suitable for panel-mounting, and incorporates a plastic body and metal actuator. The actuator has an operating temperature of -25 to 85 C. The switch is rated for current of 12A, and provided with solder-type terminals for wiring connections. It also has an IP67 rating, meaning it is water and moisture resistant to a moderate degree.The A3PA-90A11-28 switch is designed to work in a variety of circuits containing both AC and DC voltages up to 500V. Its contact rating is 12A at 28VDC, and it is designed to work with resistive, inductive, triac, SCR and generator loads. The switch can be used in many types of applications such as industrial control circuits, consumer products, automotive control systems, medical equipment and office automation. In such applications, the A3PA-90A11-28 provides reliable long-term performance and durability. When using the A3PA-90A11-28, it is important to be aware of its working principle. The switch is designed to open or close an electrical circuit when the switch is momentarily pressed. The contacts of the switch are made of a silver alloy material to provide excellent electrical performance. The metal actuator ensures that the switch is held in the closed position and also ensures that the contacts remain in contact at all times. The actual working principle of the A3PA-90A11-28 switch depends on the application circuit. In most circuits, an electromagnet or a lid-mounted actuator is used to move the contacts. The electromagnet is operated by a low voltage power supply, while the lid is actuated by the rotation of a knob or lever. When the switch is manually operated, the actuator moves the contact points together to close the circuit. When the actuator is released, the contacts open again, breaking the circuit. The contact points are designed to be oxidized quickly so that they are not damaged during switching.In summary, the A3PA-90A11-28 is a one position, small-size, momentary action, button-style pushbutton switch with a compact size of 28mm in length and 18mm in width. It is suitable for panel-mounting and has a rated current of 12A. It is used in home appliances, consumer products, automotive and office automation and is designed to work in a variety of circuits containing AC and DC voltages up to 500V. It has a reliable long-term performance and its working principle is based on an electromagnet or a lid-mounted actuator.
