Abstract: To create a snap-action switch (1) that provides separate solutions for the mechanical function of "switching" and the electrical function of "contact bridging", the snap-action element (4) is designed as one piece made of round wire and a contact element (5) is held within the snap-action element (4).

Abstract: A hydraulic damper of the monotube type in which the floating piston includes a first valve allowing fluid flow from the compression chamber to the compensation chamber when fluid pressure in the compression chamber exceeds that in the compensation chamber by a predetermined amount, and a second valve allowing fluid flow from the compensation chamber to the compression chamber when fluid pressure in the compensation chamber exceeds that in the compression chamber by a predetermined amount. Provides improved high speed damping.

Abstract: A suspension strut comprising a tube substantially closed at both ends and containing fluid; a piston assembly slidably mounted in the tube and making a sealing fit therewith, the piston assembly separating a compression chamber and a rebound chamber within the tube; a piston rod attached to the piston assembly and extending through the rebound chamber and out of one end of the tube; and a rebound stop mounted on the piston rod between the piston assembly and one end of the tube, the rebound stop comprising a substantially rigid ring and an annular bumper, wherein the rebound stop is engageable with one end of the tube and with the piston assembly.
Abstract: In order to improve a method for monitoring movable elements, in particular windows and sunroofs in motor vehicles, such that an object clamped between the movable parts and the part at rest is detected in a reliable fashion, the force acting upon such objects is maintained at the lowest possible value and the direction of the window is inverted as rapidly as possible. In order to ensure a reliable protection, a cutoff threshold consists of a constant component and a variable component, with the size of the difference (Dn) between the cutoff threshold and the instantaneous value of the rotation time (tu) influencing the switching signal.
