SUNGMUN NSI-21HS: The Versatile On-On Slide & Jumper Switch

This 3-pin NSI-21HS is more than just a slide switch; it's a manual jumper switch for your PCB. It provides two stable On positions, allowing you to create two different circuit configurations - perfect for selecting between modes or turning a circuit branch on and off.

Dual-Function Circuit (On & On):

Mode Change Setting: Example: Select between I2C or SPI communication protocols on a development board.

Power On-Off Function: Example: Control power to a specific module, like a LTE modem in a smart meter.

Key Features & Wiring Flexibility:

Acts as a Manual Jumper: Replaces a standard jumper cap with a more secure and switchable connection.

Clear Circuit Diagrams: Simple 3-pin layout (Common, Output A, Output B) for easy integration into your design.

Versatile Mounting: Available in SMD (for breadboards and compact designs) and THT types for robust connections.

Compact & Durable: Ideal for dense motherboard layouts and industrial controls.
