An electrical switch includes a fixed electrical contact; a movable electrical contact which is moveable relative to thereto between an ON position in contact with and, an OFF position out of contact with, the fixed electrical contact; a contact mover movably coupled to a terminal member moveable relative thereto so as to move the movable electrical contact between the ON and OFF positions; a biasing member coupling the contact mover and the terminal member together such that said biasing member acts upon the contact mover as the contact mover moves the movable electrical contact relative to the fixed electrical contact between the ON and OFF positions; wherein in the ON position, electrical current flows along a path comprising the terminal member, contact mover and movable electrical contact in series, and, an electrical insulation member arranged in series with the biasing member between the contact mover and the terminal member.
