INSTALLING THE PRESSURE SWITCH

This pressure switch is only compatible with guns having metal or polymer 

construction. Do not use on guns with a wooden stock.
1.  Unscrew and remove the tail cap.
2.  Screw on the tail cap attached to the pressure switch.
3.  Test the pressure switch for proper operation.
4.   Install pressure swtich pad. Proper installation is essential for user safety and long-

term use.
a)   Attach the Velcro® strip to the pressure switch. To ensure best alignment of 

the two gripping surfaces, attach both strips together, then remove one of the 

adhesive covers to expose the adhesive side. Attach this side to the pressure 

switch body. 

b)   Thoroughly clean the area on the gun where the pressure switch will be mounted. 

Use appropriate solvent to remove oil and grease. 

c)  Clean area again with the alcohol wipe provided.
d)   After the light is mounted on the gun, form the wire lead to the pressure switch 

location. Remove the remaining adhesive cover and press the pressure switch to 

the side of the gun.

e)  Retest switch for proper function.
f)   Ensure that the pressure switch does not interfere with the trigger or safety 

mechanism.
