Product details

Product Description

The Tactile Push Button Switch 21mm Long Shaft (SW-12III) is an extra-long actuator tactile switch, designed for applications where maximum button reach is required.

With its 21mm actuator height, this switch is ideal for very deep panels, thick enclosures, industrial equipment, and custom-built electronic systems. It allows reliable operation even when the switch must extend through long front panels or protective casings.

This momentary tactile push button activates only when pressed, making it suitable for signal input, control interfaces, and user-operated electronic devices. The 4-pin through-hole design ensures secure mounting on PCBs and stable electrical performance.

Due to its extra-long shaft, this switch is widely used in industrial electronics, DIY electronics, Arduino projects, and custom control systems, especially where standard-height switches are too short.

This 21mm tactile switch is one of the longest standard tactile switches available, making it highly useful for specialized electronic applications.
