The KSR221GLFS is a tactile switch manufactured by C&K. It is designed for applications requiring momentary contact, such as keyboards, control panels, and consumer electronics.
- Pin Count: The KSR221GLFS typically has 4 pins. These pins are used to provide electrical connection points for the switch.
- Function: The switch functions as a Single Pole Single Throw (SPST) momentary switch. It is normally open, which means the circuit is open (off) when the switch is not being pressed. When pressed, the switch closes the circuit, allowing current to flow. This action is used to send a signal or perform an action such as typing a character or turning on a device temporarily.
The compact design and tactile feedback make it suitable for applications where space and user interaction are considerations.
