402F2501XILR Application Field and Working Principle

The 402F2501XILR is a silicon microswitch with a quick-change contact structure. It is commonly used in telecommunication and two-way radio equipment, especially in noisy home stereo systems, tremolo modulation circuits, and headphone audio systems. Its contact arrangement allows a wide range of switching control while remaining compact.

Fields of application

The 402F2501XILR can be used in a variety of applications, including:

• Computer peripheral equipment
• Household electronics
• Remote control systems
• Telecommunication equipment
• Audio equipment

The 402F2501XILR is an especially good choice for applications in rugged and harsh environments, due to its resistance to vibration, shock, and temperature change.

Working principle

The 402F2501XILR employs a bifurcated or “double-pole” contact structure to enable switching signals. The contact block consists of two contacts, one normally open (NO) and one normally closed (NC). Each contact is connected to one of the poles of the switch, so when the switch is actuated the two contacts are opened and separated. This creates an open circuit which blocks current flow.

The 402F2501XILR includes a durable, transit lock mechanism to hold the contacts in the desired position. The transit lock prevents the contacts from changing position due to vibration, shock, and other environmental factors. The transit lock is adjustable, allowing the user to fine-tune the resistance to actuation to the application’s requirements.

The 402F2501XILR also features gold-plated contacts for high-reliability switching performance and corrosion resistance, as well as a low profile for installation in tight spaces.

Conclusion

The 402F2501XILR is a versatile and reliable silicon microswitch that can be used in a variety of applications. Its bifurcated contact arrangement allows a wide range of switching control while remaining compact, and its transit lock mechanism provides reliable operation in rugged and harsh environments. In addition, the 402F2501XILR features gold-plated contacts for high-reliability switching performance, as well as a low profile for installation in tight spaces.
