This momentary-contact pushbutton switch can be used to activate most brands of electrically-activated fire suppression systems. The included plastic shroud collar minimizes the risk of accidental actuation, but it has a large enough ID (7/8") to allow easy access when wearing driving gloves.
Mounts in a 3/4" hole in your dash panel. Requires less than 1 1/8" clearance behind the dash panel. The protective collar measures 13/16" deep x 1 5/16" OD. Screw clamp terminals allow you to connect unterminated wires. Not recommended for heavy electrical loads (starter, horn, etc).
Tip: Drill two holes in the collar, approximately 1/4" from the outer edge and directly across from each other. This will allow you to insert a safety pin (not included) to positively prevent curious fingers from setting off the system.
