Built-in tumbler switch with forcible opening of contacts - is movable between open and alternative closed positions defined by entry of spring plunger into notches on intermediate wall

摘要

The insulating housing (1) is provided with a dividing wall (6) between fixed contacts (11) with three notches (5) in its top edge for the spring plunger (4) of a projection (3) from the rocking lever (2). The moving contacts (10) are formed at the ends of resilient arms (9) forced apart by studs (8) bearing against the outside walls of the projection. One pair of contacts is 'made' in the middle position and the other pair in one end position. In the other end position, both pairs of contacts are open. USE/ADVANTAGE - For two different sequential switching functions, contact-making and breaking are guaranteed with security and more precise timing.
