A switch ( 100 ) comprises a dielectric housing ( 1 ), a number of stationary contacts ( 2 ) disposed in the housing ( 1 ), a moveable contact ( 3 ) and a slide element ( 4 ) movably mounted in the housing ( 1 ), a spring ( 5 ) disposed in the housing ( 1 ), and a cover ( 6 ) attached to the housing ( 1 ). The housing ( 1 ) defines a bottom wall ( 11 ) and four side walls extending from the bottom wall ( 11 ), the bottom wall ( 11 ) of the housing ( 1 ) having a locating post ( 16 ) cooperating with a side wall of the housing ( 1 ) to confine the spring ( 5 ). The slide element ( 4 ) defines a slide groove ( 420 ) which receives the locating post ( 16 ) so as to guide the spring ( 5 ) in the housing ( 1 ) steadily.
