An electrical switch comprising a push-button 210, a rocker switching mechanism having a rocker member 110, resilient urging means 320 and drive conversion means for converting motion of the push button 210 into motion suitable for changing the operation modes of the rocker switching mechanism, wherein, the drive conversion means operates as an interface between the push-button 210 and the rocker member 110 whereby switching modes of the rocker switching mechanism can be changed by the drive conversion means in response to motion of the push button 210, the resilient urging means 320 is disposed between the push-button 210 and the rocker switching mechanism and is adapted for providing a resilient resistive force against motion of the push button 210 towards the rocker member 110, for returning the push button 210 towards a spring neutral or zero displacement position and for providing an additional resilient resistive force to the drive conversion means whereby differential actuation force required to overcome inertia of the rocker member 110 in order to bring the rocker member 110 into a switching motion is reduced, and wherein the resilient urging means 320 comprises primary and secondary resilient urging means 320, the primary resilient urging means 320 is adapted for returning the push button 210 towards its spring neutral or zero displacement position and the secondary resilient urging means 320 is adapted for returning the drive conversion means towards a pivotally neutral position which is intermediate positions at which the switching modes of the rocker switching mechanism will be changed by the drive conversion means.
