Pushbutton Switches: The MPS-203R application field and working principle

Pushbutton switches are electrical devices that are typically used to activate or deactivate a circuit. While often used to control small household appliances and in various industrial equipment, pushbutton switches are also used in military and aerospace applications. In order to ensure reliable performance in a variety of environment, a range of pushbutton switches are available, each designed to suit a specific application. The MPS-203R is one such product manufactured by Microsemi Corporation, and it is specifically tailored for use in space and aerospace industries. This article will discuss the MPS-203R application field, followed by its working principle.

MPS-203R application field

The MPS-203R is a single pole double throw (SPDT) pushbutton switch designed to meet the challenging requirements of aerospace industries. It is designed to have a long life and superior reliability, enabling it to function in the most rigorous aerospace environments. The MPS-203R is available with multiple design features including environmental sealing, tamper-proof construction, and specialized mounting hardware. The switch is also available with a wide range of contact configurations, making it suitable for various applications. Common application fields for the MPS-203R include aircraft instrumentation, military aircraft, and spacecraft.

Working principle

The MPS-203R is a contact-style switch, which means that it consists of two terminals and a movable contact. When the switch is closed, the contact is touching both terminals and a circuit is completed, allowing current to flow. When the switch is open, the contact is not connected to either of the terminals and the circuit is broken, preventing current flow. The MPS-203R is designed to switch between modes quickly and efficiently while also having a secure locking mechanism that prevents accidental activities.The MPS-203R is actuated by a single pushbutton. When the button is pressed, the contact moves along a metal shaft and connects to the other terminal. The metal shaft also features a detent mechanism, which helps to lock the contact in place so that it does not accidentally disconnect. The MPS-203R also features a plastic support that prevents the contact from shifting or bouncing, ensuring that the switch stays in the desired position at all times.

Conclusion

Pushbutton switches, such as the MPS-203R, play an important role in the aerospace industry. These switches are designed to be reliable, secure, and highly durable in order to function in even the most demanding applications. The MPS-203R is a type of SPDT switch designed specifically for aerospace use, and it is capable of switching between modes quickly and efficiently. By understanding the MPS-203R application field and its working principle, designers, engineers, and technicians can make informed decisions when it comes to selecting the right switch for their project.
