ABSTRACT:
A micro-switch having an actuating mechanism comprising a slide member which is movable longitudinally of itself in the switch casing and engages the electrical switching element, and a pivoted actuator which extends externally of the switch casing and comprises a length of wire which is pivoted in a hole in the switch casing and which has a bent end portion within the casing which is connected to the slide member so that pivoting of the actuator in one particular sense causes the slide member to move longitudinally to operate the switching element. Preferably, said end portion of the wire is connected to the inner end of the slide member by engaging an aperture or recess in the latter. The recess is conveniently a transverse channel formed in the side face of the slide member which is exposed on removal of a switch cover. That portion of the wire projecting from the other side of the casing can be bent through 90.degree. so as to form an operating arm which can readily be pointed in any direction and may be of any length.
