Abstract: A multi-directional operating switch assembly includes: a recessed base; first and second switches disposed in the recessed base; a slider disposed in the recessed base and having a main part and a protrusion protruding from the main part, the slider being slidable in a first direction so as to actuate the first switch; an operating lever having a slot defined by a slot-defining wall, the protrusion of the slider extending into the slot, the operating lever being movable in the first direction to drive the slider to move in the first direction, and being further movable relative to the slider in a second direction to actuate the second switch; and an urging member disposed in the slot and abutting against the protrusion and the slot-defining wall.

Abstract: An inclinometer includes a base, a weight, and a magnetic field-detecting unit. The weight is provided with a magnet and is pivotally suspended from the base in such a manner that the base and the weight are rotatable relative to each other. The magnetic field-detecting unit is secured to the base for detecting a magnetic field of the magnet.

Abstract: An inclination-detecting device includes a casing, a magnet, and a magnetic field detecting unit. The casing is formed with a cavity therein. The cavity is defined by a cavity-defining wall that has equal numbers of sides and corners. The magnet is disposed movably in the cavity in the casing. The magnetic field-detecting unit is mounted on the casing.
