ABSTRACT:
An electrostatic discharge protection device can protect a head gimbal assembly circuit from electrostatic discharge. The device includes a housing and a shunt positioned within the housing. The shunt includes a pair of electrical contacts and the shunt has a first position in which the electrical contacts are in electrical communication with the circuit and a second position in which the electrical contacts are removed from electrical communication with the circuit. The shunt can be placed in its first position to protect the head gimbal assembly against electrostatic discharge and is moved into its second position to permit testing operations of the head gimbal assembly. The shunt is then returned to its first position.
