Abstract: A control ring (4) provides discrete changes in rotational position to indicate control by a switch assembly (1a) with perceivable haptic response indicating effected changes, wherein a slider (5) is provided with ability to come to an equilibrium position along an axis of rotation (A), wherein the control ring (4) is provided with a number of substantially equiangularly disposed radial protrusions (42a, 42b), wherein the slider (5) is provided with a radial protrusion (52a, 52b) that extends in an area of a circumference defined by the ring's radial protrusions (42a, 42b), wherein the equilibrium position of the slider remains between two adjoining radial protrusions (42a, 42b) of the ring, wherein the radial protrusion (52a) of the slider (5) has a form of a cam (8) having two angularly external surfaces (81, 82) slanted at the same orientation (?1, ?2) with respect to the plane containing said axis of rotation (A).

Abstract: In some embodiments a ternary electrocatalyst is provided. The electrocatalyst can be used in an anode for oxidizing alcohol in a fuel cell. In some embodiments, the ternary electrocatalyst may include a noble metal particle having a surface decorated with clusters of SnO2 and Rh. The noble metal particles may include platinum, palladium, ruthenium, iridium, gold, and combinations thereof. In some embodiments, the ternary electrocatalyst includes SnO2 particles having a surface decorated with clusters of a noble metal and Rh. Some ternary electrocatalysts include noble metal particles with clusters of SnO2 and Rh at their surfaces. In some embodiments the electrocatalyst particle cores are nanoparticles. Some embodiments of the invention provide a fuel cell including an anode incorporating the ternary electrocatalyst. In some aspects a method of using ternary electrocatalysts of Pt, Rh, and SnO2 to oxidize an alcohol in a fuel cell is described.
