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.
