Abstract

1. Manually operated overload protective switch, in particular permetering switch, having trip-free release and the following features : an extended contact bridge (4; 104; 204) which is springloaded (contact spring 2; 102) on one side is arranged in a switch housing (1; 101; 201), the pivot movement of which contact bridge (4; 104; 204) can be manually controlled in the switch plane by a handle (rocking lever 8), which contact bridge (4; 104; 204) interacts with a fixed contact (3; 103) to close the current path, in the switch-on position, at its contact-remote end (retaining arm 14; 114; 214), can be locked (locking position) in a first position by a ratchet lever (6; 106; 206) interacting with a tripping device, and can be supported approximately in its centre area on one side to form a central pivot bearing (contact bridge bearing 15) supporting a two-arm lever, characterized by the following features : the handle (rocking lever 8) or an intermediate member (push rod 23) interacting with this handle acts on the contact bridge (4; 104; 204) in the opening pivoting direction for pivoting in the manner of a single-arm lever, pivotally mounted at its contact-remote end, while passing dead centre and subsequently running free in the area of the pivoting end positions of the handle, the spring (contact spring 2; 102; 202) loads the contact bridge (4; 104; 204) in the contact closing direction in the contact bridge area located between the contact-remote end and the central pivot bearing (contact bridge bearing 15, pivot bearing 170), the contact-remote end of the contact bridge (4; 104; 204), in the event of tripping, after release by the ratchet lever (6; 106; 206), pivots away in the loading direction of the contact spring (2; 102; pulling direction of the contact spring designed as a tension spring), with the contact bridge (4; 104; 204) turning as a two-arm lever while seated on the central pivot bearing or when the latter comes into effect, and the contact end lifting from the fixed contact (3; 103) under the force of the contact spring (2; 102).
