Claim:
1. A haptic feedback device for generating haptic sensations to a user of the device, comprising: a first solenoid coil and a second solenoid coil disposed with a space between the first and second coils, each coil having an open core and connections for supply of electrical current through the coil to energize the coil to generate a magnetic flux; and a plunger disposed to move in an axial direction in the space between the first and second coils upon energization of one or more of the coils in response to the magnetic flux, the plunger having a first end disposed to move within the core of the first coil and a second end disposed to move within the core of the second coil, wherein upon energization of the first coil, the magnetic flux causes the plunger to move toward the first coil so that a part of the plunger engages with the first coil to generate haptic sensations to the user.
