The trigger mechanism on the Empire Mini GS relies on a microswitch that is housed within the grip frame. To activate the microswitch manually, release the trigger and press the microswitch button located near the trigger pull. The button should click and the microswitch should be in the activated state. If the trigger pre‑travel is holding the microswitch in the activated position, the solenoid will not click. To test the microswitch, disable the trigger pre‑travel by pulling the trigger to the end of its travel and release it. The microswitch should return to the de‑activated state. If the microswitch remains activated, the trigger pre‑travel is likely mis‑aligned. Adjust the trigger pre‑travel by loosening the trigger screw and sliding the trigger until the microswitch is fully de‑activated at the end of the travel. Once the microswitch is correctly positioned, the solenoid should click when the trigger is pulled. If the solenoid still does not click, the microswitch may be defective. Replace the microswitch with a new one from the OEM parts list. After replacement, re‑install the trigger and test the solenoid again. If the solenoid clicks, the trigger and microswitch are functioning correctly. If the solenoid does not click, contact Empire support for further diagnostics. The microswitch is a critical component of the Mini GS and must be functioning correctly for safe operation. Keep the microswitch clean and free of debris to ensure reliable operation. During operation, always ensure the trigger is fully retracted before recharging the battery. The microswitch should be inspected for any signs of wear or corrosion. If corrosion is present, clean with a mild abrasive pad and apply a thin layer of silicone grease to the contacts. This will reduce resistance and improve reliability. Additionally, verify that the trigger lever is not binding on the frame; if binding occurs, adjust the trigger spring tension accordingly. A properly adjusted trigger will provide a smooth pull and consistent solenoid activation. Finally, test the trigger and microswitch after every major upgrade or modification to confirm that the system remains within specifications. This routine maintenance helps prevent unexpected failures during critical operations.
