Key Pad Instrument Normally Closed Tactile Switch With 2.54MM Pitch
Female Connector
Features
Compact Design: These switches are typically small and can fit into various
electronic devices, making them popular in portable applications.
Normally Closed State: The switch allows current to flow in its default position. It
interrupts the circuit when pressed.
Tactile Feedback: Like other tactile switches, it provides a physical click or
feedback when actuated, ensuring users know that the switch has
been activated.
Applications
- Control Circuits: Often found in devices where a default state (on) is required
until a specific action is taken.
- Safety Devices: Commonly used in emergency stop buttons where pressing the switch
should stop a machine or circuit.
- Alarm Systems: Can be used in security systems to trigger alarms when a door or
window is opened.
Considerations
- Debouncing: Consider implementing debouncing in software or hardware to avoid
multiple triggers from a single press.
- Circuit Design: Ensure that the circuit is designed to account for the normally
closed operation, as it will behave differently from normally open
switches.
