A switch module includes a switch base, a common terminal, a normally open terminal, a resilient piece, an upper cover and a soft element. The resilient piece includes a first portion and a second portion. The first portion of the resilient piece is disposed on the common terminal. The second portion of the resilient piece is located over the normally open terminal. The upper cover is disposed on the switch base to cover the common terminal, the normally open terminal and the resilient piece. The soft element is arranged between the upper cover and the second portion of the resilient piece. When an external force exerted on the resilient piece is eliminated, the second portion of the resilient piece is moved in a direction away from the switch base in response to an elastic restoring force of the resilient piece.

A waterproof button module includes a casing, a button, a resilient member, and a first waterproof portion. The casing has a first recess and a first through hole located at a bottom of the first recess. The button is located in the first recess and partially passes through the first through hole. The resilient member is located in the first recess. The button and the bottom of the first recess are respectively located on opposite sides of the resilient member. The first waterproof portion surrounds the first through hole and abuts against the resilient member and the first recess in an airtight manner.

A module includes a permanent magnet biased electromagnetic haptic engine having a stator and a rotor; a constraint coupled to the stator and the rotor; and a force sensor at least partially attached to the permanent magnet biased electromagnetic haptic engine and configured to sense a force applied to the rotor. The constraint is configured to constrain closure of a gap between the rotor and the stator and bias the rotor toward a rest position in which the rotor is separated from the stator by the gap.
