Intellitronix
Digital RPM 3 Mode Window Switch is ideal for nitrous
applications allowing you to activate nitrous at a predetermined RPM and have
it shut off before it reaches the peak RPM. The Digital RPM 3 Mode Window Switch with digital
technology uses Push Buttons and Digital Display to program the
switch and works with 1, 2, 4, 6, 8, 10, and 12-cylinder engines with an RPM range
2000 to under 10,000 RPM. The RPM Switch functions as a Digital Tachometer with
high RPM recall function.
