A mechanical shunt for use in a socket of a string of lights resides in an otherwise typical lamp of a string of lights. The present shunt is a pair of cantilevered portions from the electrical terminals inside the socket of a lamp in a string of lights. The portions touch and conduct electrical current when no lamp holder is in the socket but are separated by a button on the bottom of the lamp holder when the lamp holder is not in the socket. The cantilevered portions are formed in such a way that they rub together when opening, closing or when the socket undergoes expansion and contraction with changing temperature in order to prevent the buildup of corrosion on the teeth on the end of the cantilevered portion that would preclude their ability to make good electrical contact when needed.
