PSF109S Series High Current Vacuum Switch

This is the high quality vacuum switch most recommended for use with HHoGreenMachine kits to be used for the purpose of serving as a redundant safety measure to prevent the possiblity of an HHo failure incident . It is mandatory that all HHoGreenMachine kits are connected to the fuel pump relay circuit to ensure that these kits provide a Browns Gas "hydrogen on demand" service capability. However the use of a vacuum switch is also highly recommended (and is mandatory for all vetted HHoGreenMachine kit installs) as well for the purpose of acting as a redundant safety backup against any possibility of an HHo failure incident. All operating internal combustion engines internally develop a vacuum and this vacuum is used to activate this type of a switch which will also ensure that your HHo system cannot and will not operate unless your installed to vehicles engine is also operating (and creating a vacuum) as well. These switches will work with either 12 or 24 VDC vehicle systems (actually a snap action basic switch that operates with limits up to 25 amps / 125 & 250 VAC), have a dependable long life (10+ million cycles) and has a quarter inch size vacuum port.

   $57.00 plus $5.50 S & H (USA ONLY)
