Digital RPM 3 Mode Window Switch N3211
 
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 RPM Activated 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. 
 
This uniquely designed Digital RPM 3 Mode Window Switch functions as a tachometer with high RPM recall and features over-current protection, short-circuit protection, and over-voltage protection. The Push Buttons and Digital Display are easy to use to program the switch and has three modes available to set.
 
Digital Switch Mode (1 Limit): 
 
The one (1) limit allows the entry of one RPM value. If the RPM is over the value entered, it will activate the switch. If the RPM registers below the entered value, the switch will deactivate.
 
Window Activated Mode (2 Limits):
 
The two (2) limits allows two limits to be set. First is the low limit and second is the high limit. If the RPM registers between the lower and higher limit, the switch will activate. If the RPM registers outside the two limits, the switch will deactivate.
 
Activated Mode (2 Limits Bottom Entry):
 
This mode functions the same as the two (2) limit window mode with the exception that once the RPM is outside the two set window limits, it will only reactivate once it enters the window from the low limit on the bottom side.
 
Note: This will not work with a deisel tach signal
