This is a pack of seven transmitter spring contacts for the Traxxas TQ series of transmitters. Three contacts are replacements for the the "crystal side" contacts in your transmitter battery compartment. The remaining four contacts are for the "on/off switch side" of the transmitter battery compartment.
Installing a Spring Contact:
- Locate the positive (+) and negative (-) symbols imprinted on the battery compartment.
- Slide the contact into the slots below the symbols. The "tall spring" should go into the negative (-) slot, the "flat spring" should go into the positive (+) slot.
- Using your finger, push the contact into the slots until the bar which connects the springs slides under the center tab.
