The Double Apex Water | Meth Button is the OEM+ solution for operating your water-methanol injection system. The button lighting, feel and finish match perfectly with your Volkswagen’s interior like it was factory equipped.

The red and amber LEDs match the factory color scheme and make it easy to tell what mode your system is in. The red LED illuminates with the other interior lights and the amber LED will indicate if the system is on or off. 

The momentary push button is available with a relay module that will let you toggle between two modes, like on / off, or with a simple wiring harness for custom applications..

About the options:

The Water | Meth Button can be configured to provide momentary or toggle switching functionality and can be used in a wide range of applications. The options are described in detail below. These kits do not include wiring for a specific system. Please verify compatibility with your application before ordering. If unsure, please contact us for advice on your setup. 

Toggle Kit: Includes a 10 amp toggle relay. This allows on / off functionality of any 12 volt device. The relay module can be used to switch the power or ground wire of the switched device.

Momentary Kit: Includes a momentary function push button with a generic wire harness. The switch function is “Off-Mom”, meaning it is normally off, and on only while the button is pushed down. It does not latch in the on position like a toggle switch would. It’s typically used in custom installations where it will be paired with a control circuit that accepts a pulse signal.

The switched leads are 56" long, as is the power lead for the amber LED. The leads for the red LED are designed to connect to the local button lighting circuit. For low amperage signal and switching currents only, <100mA. For higher currents a relay must be used. Please contact us if you need advice on your application.
