An electrical switch comprising an actuation member (140, 240), wherein said actuation member (140,240) comprises an actuating lever (142, 242) and an urging means, wherein said actuating lever (142, 242) is mounted on a switch housing (160, 260) and pivotally movable relative to a switch housing to move between said on- and off- positions, the electrical switch further comprising a switching mechanism, wherein said actuation member is movable between a first position and a second position corresponding respectively to on- and off- positions of said switching mechanism; wherein said actuation member is arranged such that a two-stage movement is required to move said actuation member from said second position to said first position to operate said switching mechanism, wherein said switch comprises a guide means, which comprises a guide track (166, 266), defining a path along which said actuation member is moveable between said on- and off- positions, and one-way barrier means formed on said guide means; and wherein said one-way barrier means is configured such that said actuation member is moveable from said on- position to off- position unobstructed by barrier resistance of said barrier means, and said actuation member is moveable into engagement with said guide means and then from said off-position to said on-position after overcoming barrier resistance of said barrier means, wherein the two-stage movement comprises a first-stage movement in a first direction to move said actuation member from said off- position into said guide track, said first-stage movement comprising an axial movement of said actuator member along its longitudinal axis to move said actuation member, against spring urge towards said housing and said guide track and a second-stage movement in a second direction different from the first direction, to move said actuation member along said guide track to said on- position and second-stage movement comprising a pivotal movement to move said actuation member towards said first position, wherein said guide track discontinues at an entry end at which said actuation member transits between said off- position and said guide track, said discontinuity forming a one-way barrier against movement of said actuation member from said off- position towards said guide track, and being a non-barrier to a said actuation member with respect to movement of said actuation member from said guide track towards said off- position, wherein said guide means is arranged such that, when said an actuation member is at said on- position, a said actuation member is in engagement with said guide means and is urged by said guide means to close said a switching mechanism, and a said actuation member is released from engagement with said guide means when at said off- position, wherein the urging means is arranged to urge a said actuation member out of engagement with said guide means when at said off- position, characterised in that said guide means are formed on housing (160, 162), the guide track being moulded on said housing (160, 162), said actuating lever comprises a pair of transversal protrusions arranged to engage with said guide means, said pair of transversal protrusions being in engagement with said guide means when moving between said on- and off- positions, and said pair of transversal protrusions being released from engagement with said guide means at said second position, said actuator member further comprises an actuating tongue, said actuating tongue being moveably mounted to said actuating lever and protruding axially there-from, and wherein said actuating lever and said actuating tongue are arranged such that the extent of axial protrusion of said actuating tongue from said actuating lever changes as said actuating lever moves from said off- position to said on- position, the urging means is a helical spring which is substantially coaxial with a bore of the actuation lever and disposed intermediate said actuation tongue and the top end of the bore, said actuating tongue is coupled to said actuating lever against the axial urge of the urging means which urges said actuating tongue to move away from said actuation lever along the axis of said actuation lever, and said actuation member is arranged such that action of said actuation tongue on said switching mechanism urges said actuation lever against said guide means to engage therewith, said switching mechanism comprises a conductive bridge (124, 224) which is arranged to toggle between said one and off positions in response to sweeping movement of said actuation member between said on- and off- positions, and said conductive bridge is in sliding contact with said actuation member and in compressive contact with said actuation tongue due to the spring urging means when said actuation member moves between said on- and off- positions, so that the urging means is arranged to urge said actuation member to close said switching mechanism when at said on position.
