    (54) Electric lock provided with an opening handle which acts directly on the spring latch


    (57) The electric lock comprises a spring latch (11), a reloading piston (12) and an element (14) which is guided in said casing parallel to said piston. The spring latch (11) comprises a stem (32) which is guided in said sliding element and has an end provided with engagement means (34) for said sliding element (14) which are suitable to pull the spring latch (11) into the casing (1) during the opening step. Spring means (39) act on said spring latch to keep said sliding element in abutment against a fixed stroke limiter (33) at which said spring latch protrudes from said casing (1). The stem (32) connects to the hub (42) of the handle so that actuation of the handle causes retraction of the spring latch (11) in contrast with the action of said spring means (39).
