Main switch for electrical systems of vehicles
A main switch for electrical systems of vehicles, comprising an outer casing projecting from which is a plurality of electrical contacts that are to be connected to cables of the electrical system, wherein the casing has a base that is to rest on a supporting plate of the vehicle, said base being fixed by means of screws to the supporting plate, wherein the base is provided with two pairs of fixing elements having respective holes that are to be engaged by said screws, said fixing elements being insertable in the respective seats of the base in two different positions to which there correspond different distances between the centers of the fixing elements of each pair.
1. A main switch for electrical systems of vehicles, comprising an outer casing, projecting from which is a plurality of electrical contacts that are to be connected to cables of the electrical system, wherein the casing has a base that is to rest on a supporting plate of the vehicle, said base being fixed by means of screws to the supporting plate, wherein the base is provided with two pairs of fixing elements having respective holes that are to be engaged by said screws, said fixing elements being insertable in seats of the base in two different positions to which there correspond different distances between the centres of the fixing elements of each pair, and wherein each of said fixing elements has a bottom portion with a rectangular cross section that fits with two opposite orientations in a through opening of each seat.
2. The main switch according to claim 1 , wherein the axis of the hole of each fixing element is shifted with respect to the centre of said bottom portion with the rectangular cross section.
3. The main switch of claim 1 , wherein the fixing elements include a head having a round cross section, the head coupled to the bottom portion.
4. The main switch of claim 3 , wherein the head is adapted to rest upon an upper surface of the seat.
5. The main switch of claim 4 , wherein the head of each fixing element includes an upper portion having the round cross section, and a lower portion having two linear sides.
6. The main switch of claim 1 , wherein the through opening of the respective seat is rectangular.
