ABSTRACT:
This potentiometer has a pair of insulating standoffs integrally formed with the body of a model or toy incorporating the potentiometer. An insulated trough extends between the standoffs. A resistive element wound around an insulating core is disposed in the trough. A resilient contact element is slidably mounted engagement with the resistive element. Means extends through the body of the model or toy for sliding the resilient contact element along the resistive element. This potentiometer has major portions of its assembly formed in a molding operation used to form the body of the model or toy, and can be assembled by hand without the use of special tools.
