摘要:
A switch, in particular a battery cutout switch for vehicles and the like, comprising: - an insulating housing (12) carrying at least two fixed electrical contacts (22), - a contact-holder body (28) movable relative to the housing (12) along a rectilinear direction (A) between a closed contacts position and an open contacts position, - at least one movable electrical contact (32) carried by said contact-holder body (28) and having a first and a second contact zone (70, 72), cooperating with the head portions (23) of the respective fixed electrical contacts (22),
wherein said first contact zone (70) of said movable electrical contact (32) has two protuberances (76) with curved contact surfaces that establish two points of contact with the head portion (23) of the respective fixed electrical contact (22), and said second contact zone (72) has a single protuberance (78) with a curved contact surface that establishes a single point of contact with the head portion (23) of the respective fixed electrical contact (22), so that in the closed contacts position, said movable electrical contact (32) is in contact with said fixed electrical contacts (22) at three points.

A switch, in particular a battery cutout switch for vehicles and the like, comprising: - a housing (12) carrying at least one pair of fixed electrical contacts (22), - a contact-holder body (28) carrying at least one movable electrical contact (32), the contact-holder body (28) being movable along a longitudinal axis (A) between an open contacts position and a closed contacts position, - elastic means (38) arranged between the housing (12) and the contact-holder body (28) and tending to push the contact-holder body (28) towards the open contacts position, - a handle (44) rotatable about said longitudinal axis (A) between an open position and a closed position, - a cam (64), fixed with respect to said contact-holder body (28),
wherein the handle (44) cooperates with said cam (64) to move said contact-holder body (28) from the open contacts position to the closed contacts position to the closed position, upon rotation of the handle from the open position to the closed position, wherein said cam (64) has at least one first and at least one second active surface (70, 72), and said handle (44) has at least one first control member (54), which cooperates with the first active surface (70) and at least one second control member (56) which cooperates with the second active surface (72), said first and second active surfaces (70, 72) and said first and second control members (54, 56) being arranged in such a way that when the handle (44) rotates from the open position to the closed position, the first control member (54) cooperates with the first active surface (70) to move the contact-holder body (28) from the open contacts position to the closed contacts position, and when the handle (44) rotates from the closed position to the open position, the second control member (56) cooperates with the second active surface (72) to move the contact-holder body (28) from the closed contacts position to the open contacts position.
