PBS-11B 12mm Momentary Self-Reset Round Push Button Switch (Red) – 2-Pin Normally Open (NO) Micro Switch for Horns, Resets, and DIY Electronics

Product Description The PBS-11B is a high-quality momentary round push button switch designed for applications requiring a temporary electrical connection. Unlike the "A" version (latching), this Self-Reset switch only remains "ON" as long as your finger is pressing the button. Once released, it automatically springs back to the "OFF" position. This functionality is essential for the engineers at Robogears Pvt Ltd when designing reset triggers for microcontrollers, pulse signalling for industrial machinery, or horn/buzzer triggers in automotive and robotics projects.

Key Highlights

• Instant Self-Reset Action: The internal spring mechanism ensures the button returns to its original state immediately after use, preventing accidental continuous power flow.

• Threaded Panel Mount: The 12mm diameter body allows for easy installation into any plastic or metal chassis. It includes a mounting nut and washer to ensure it remains stationary during heavy use.

• Vibrant Red Actuator: The domed red button provides high visibility and a large surface area, making it easy to operate even in fast-paced environments.

• Compact Footprint: Small enough to be used in handheld devices, yet robust enough to handle standard AC mains voltages for light-duty signalling.

• Reliable Contact Points: Built with silver-plated terminals to minimise contact resistance and ensure a clean electrical signal every time the button is depressed.
