What are the key features of KSR251G?
- SPST-NO tactile switch rated 50 mA at 32 V DC, providing reliable low-current signal switching with defined actuation force
- Audible and tactile click feedback confirms switch actuation, reducing operator error in panel-mount and PCB-mount user interface designs
- C&K industrial-grade construction with gold-plated contacts ensures consistent contact resistance over the rated electrical and mechanical life cycles
What is KSR251G used for?
The KSR251G is designed for user interface panels, consumer electronics, and industrial control equipment where momentary contact switching at low current levels is required. Its tactile feedback and compact footprint make it ideal for front-panel controls on test instruments, medical devices, and handheld remote controls operating at logic-level voltages up to 32 V.

Frequently Asked Questions
What are the electrical ratings of the KSR251G tactile switch?
The KSR251G is rated for 50 mA maximum current at 32 V DC, making it suitable for logic-level and signal-switching applications rather than power switching. These ratings are sufficient for driving microcontroller GPIO inputs, indicator LEDs through a resistor, or triggering low-power relay coils in control circuits.
For which PCB assembly methods is the KSR251G designed?
The KSR251G is designed for through-hole PCB mounting, allowing wave soldering or manual soldering assembly. Its lead spacing conforms to standard 0.1-inch (2.54 mm) grid layouts, which simplifies placement on prototype breadboards and production PCBs without requiring special tooling or custom footprints.
How does the KSR251G compare to similar C&K tactile switches for rugged environments?
The KSR251G offers a balanced combination of 50 mA current capacity and 32 V rating with tactile actuation feedback, placing it in C&K's standard reliability tier. For higher-reliability or wash-down environments, C&K offers sealed tactile variants rated to IP67; the KSR251G is optimized for dry indoor applications with a typical mechanical life of 1,000,000 actuations at rated load.
What actuation force and travel distance does the KSR251G provide?
The KSR251G typically provides an actuation force in the range of 1.6 N to 2.6 N with a travel distance of approximately 0.3 mm to 0.5 mm, delivering crisp tactile feedback. These parameters make it comfortable for frequent manual operation in panel control applications while avoiding accidental triggering from incidental contact.
