Sotac Perst-4 Dual Switch

Take full control of your Perst-4 setup with the Sotac Perst-4 Dual Switch. Designed for seamless integration with Sotac, Potted Sotac, and WADSN Perst-4, this dual-button switch provides fast, reliable access to your Perst-4 laser and compatible white light.

The dual-button design provides flexible control of your laser and white light without requiring separate switches. The top button activates your white light and Perst-4 laser simultaneously in either momentary or constant-on operation. The second button provides direct momentary activation of the Perst-4 laser in whichever mode the unit is currently set to—IR or VIS.

Important Perst-4 Dual Switch Programming Note

Due to the original programming logic of Sotac, Potted Sotac, and WADSN Perst-4 units, there is one important operational consideration when using the Sotac Perst-4 Dual Switch.

If the top button is used to activate both the white light and Perst-4 laser for more than approximately 3 seconds, the Perst-4 laser will remain activated after pressing the top button again to turn off the white light.

If this occurs, simply press the second button briefly to deactivate the Perst-4 laser.

This behavior is related to the factory programming logic of the Perst-4 and cannot be overridden through switch programming. This is an inherent trade-off when integrating dual-switch functionality with the Perst-4’s original activation logic and should be taken into consideration when operating the switch.
