Abstract
An electrical switch (1) is proposed which consists of a lower housing component (3) and an upper housing component (2). In receptacles (24) of the lower housing component (3) contact lugs (23', 23") with a normally closed contact (29', 29") are arranged. In the upper housing component (2) a contact element with a switching contact (22) is arranged. The contact element is moved, via a pressure spring (17) and a slider rod (9) to which an actuation element (5) is coupled, so as to flip between the off-position and on-position. At the contact lug (23') which is arranged on the side of the lower housing component (3) facing away from the contact element in the off-position, an arc extinction lug (32) which consists of an extension is attached to the normally closed contact (29').
Claims18
An electrical switch, comprising:
- a lower housing component and an upper housing component connectable to one another in a locking fashion, said lower housing component including contact lug receptacles;
- contact lugs arranged in respective ones of said contact lug receptacles of said lower housing component and having normally opened contacts;
- a contact element including a switching contact arranged in said upper housing component;
- a slider rod slidingly disposed in said upper housing component and having one end projecting out of said upper housing component;
- an actuation element coupled to said one end of the slider rod for moving the slider rod between first and second positions in said upper housing component;
- a pressure spring operatively arranged between said slider rod and said contact element for flipping said contact element between an off-position when said actuation element moves said slider rod in the first position in which the switching contact does not touch the normally opened contacts of said contact lugs and an on-position when said actuation element moves said slider rod in the second position in which the switching contact touches the normally opened contacts of said contact lugs, wherein one of said contact lugs is arranged on a side of said lower housing facing away from said contact element in the off-position;
- and
- an arc extinction lug comprising an extension attached to the normally open contact of said one contact lug.
An electrical switch as defined in claim 13, wherein said second part includes the switching contact.
An electrical switch as defined in claim 14, wherein the first part is adjacent to the switching contact.
An electrical switch as defined in claim 15 wherein the first part is tapered.
