Abstract:
A switch device which comprises a first contact (1), that is designed to be electrically connected to a first conductor (101) of a power line and a second contact (2), that is designed to be electrically connected to a second conductor (102) of said line, the first or the second contact being mounted in a displaceable fashion, so that said first and said second contacts (1, 2) alternately assume a mutual adhesion position, in which adhesion position electric connection is generated between said first and said second conductors of said power line, or a mutual retraction position, in which said two conductors (101, 102) are electrically disconnected from each other. The first or the second contact has a contact surface which is formed of a plurality of separate contact zones (Zi), which are connected in parallel to the conductor connected to the corresponding contact, and each of which adheres independently of one another to the cooperating second or first contact.
Abstract:
An assembly for installation of a switch in the dashboard of a vehicle without the use of any tools. The assembly comprises a housing, a resilient member such as a washer spring, and a bezel. The switch is secured to the housing and subsequently inserted into the bezel which is integrated with the dashboard. The installation of the switch, which is secured to the housing is then completed through the interaction of a profiled wall on the bezel and a flange on the housing with the washer spring interposed between.
Abstract:
A multiple electric switch (30) is formed by inserting a plurality of electrical contacts in a plurality of spaced apart (20) holes in a base (14) of electrically non-conductive elastomeric material, in groups of two pairs per group, and mounting a control member (64) in the base for movement to move one of the pair of contacts (50) of a group resiliently into engagement with the other pair of contacts of the group, to effect closing of the electric switch. A second group of electrical contacts (52) are spaced apart in a circular pattern adjacent a circular, electrically conductive contact ring, and a cam member (70) on the base is rotatable to engage and move each of the contacts, one at a time, resiliently into engagement with the contact ring. The second group of contacts are included in the electric circuit of the first groups of contact pairs to effect control of multiple movement of each of a plurality of electric loads.
