Switch grease for controllers

Take care of your controller contacts with Tamiya Switch Lubricant

Controllers and speed controllers operate under continuous cycles of opening and closing the electrical circuit. Every time we pull the trigger, the metal contacts of the switch rub against each other and generate small sparks —electric arcs— which, over time, degrade the conductive surfaces and reduce the controller's response. The Tamiya Switch Lubricant (TA87023) is specifically formulated to protect these contact points and keep them in perfect working condition.

Function and performance

This grease acts as a protective and conductive barrier at the electrical contact points of the controller:

• Prevents the formation of electric arcs, one of the main causes of premature wear in controller switches.
• Improves current flow between contacts, promoting a cleaner and more precise response from the controller.
• Extends the lifespan of the controller by reducing oxidation and mechanical deterioration of the contact surfaces.
• Formulated for use in sensitive electronics: it does not damage components or plastic materials inside the controller.

Recommended applications

Although Tamiya developed it with R/C and slot car speed controllers in mind, its application is valid for any small-sized switch or electrical contact point that requires lubrication and protection:

• Controllers and speed controllers for slot and R/C.
• Switches and buttons in modelling electronics.
• Contact points in accessories and track control units.

Usage recommendations

The application should be precise and moderate: a minimal amount of grease at each contact point is sufficient. An excess may attract dirt or interfere with other nearby components. It is recommended to clean the surfaces with a dry cloth or a cotton bud before applying the grease, especially if the controller has been in use for some time and already shows deposits of rust or dirt.

To apply, a fine stick, the tip of a precision screwdriver, or the applicator itself if included in the packaging will suffice. Once applied, operate the switch several times to evenly distribute the grease across the entire contact surface.

Frequently asked questions

How often should I apply this grease to my controller?

It depends on usage. In competitive or intensive use conditions, checking and applying it each season or when you notice the controller's response becoming irregular is a good practice. In occasional recreational use, applying it at the first signs of wear is usually sufficient.

Is it compatible with all types of slot controllers?

Yes, it is designed for metal contacts of switches in speed controllers in general. However, if your controller incorporates advanced or digital electronic components, always consult the manufacturer's instructions before applying any lubricant inside.

Can I also use it on the car's braids or guide?

No. This grease is formulated for switch contact points, not for the braids or guide of the car. For lubricating the chassis, axles, and mechanical parts of the car, there are other specific products from Tamiya and other brands.

How much do I need to apply?

Very little. A minimal amount —just the tip of a stick— is sufficient to cover a contact point. Always apply sparingly to avoid the grease migrating to unwanted areas inside the controller.

Tamiya Switch Lubricant (TA87023) is a contact grease specially designed for R/C speed controllers and slot car controllers. It prevents electric arcing, improves current flow and extends the service life of switches and electronic contact points. A must-have maintenance product for slot and R/C hobbyists looking to keep their controllers performing at their best.
