Rotary switch (1, 101) comprising: a rotor (15, 115) supporting at least one electro-conductive rotary contact bridge (19, 119); a plurality of stationary contacts (21, 121); a housing (3, 103) accommodating the stationary contacts and the rotor. The housing comprises a plurality of sides (5, 105) extending between a top side and a bottom side. At least two of these sides (5, 105) are provided with access openings (62, 62) providing access to an associated stationary contact. These sides make an angle with each other. The housing may for example be rectangular.

A rotatable device has a stationary base including bottom and top surfaces. The bottom surface has a first set of coupling electrodes configured to receive a reference signal from first electrodes of an attached input device, and second and third sets of coupling electrodes each configured to receive resulting signals from a second set of input device electrodes. The top surface of the stationary base has first, second and third top regions respectively connected to the first, second and third sets of coupling electrodes. The rotatable device further includes a rotary wheel, configured to rotate relative to the stationary base, with a bottom portion provided with alternating conductive and non-conductive regions and configured to align with the top portion of the stationary base. The resulting signals of the input device are modified by the relative positions of the stationary base and the rotary wheel.

A rotary switch structure includes a sleeve, a seat body, an elastic ring, plural push elements and a fixing element. The seat body is accommodated within the sleeve. The elastic ring is disposed on the seat body. The plural push elements are disposed on the elastic ring, and provide a pushing force to the elastic ring. The fixing element is fixed in the sleeve and contacted with the plural push elements. The plural push elements are fixed on the elastic ring by the fixing element. The elastic ring absorbs the pushing force, so that a friction force between the at least one push element and the elastic ring is adjustable. Consequently, the rotating feel of the rotary switch structure is adjustable according to the practical requirements.

A rotary encoder includes a shaft and an encoder mechanism that holds the shaft in a rotatably inserted state and detects a rotation direction and a rotation angle of the shaft. The encoder mechanism includes a substrate that rotatably holds the shaft, an insulator portion and a resistor portion provided on one surface of the substrate and alternately provided in the rotation direction of the shaft, a rotor attached to the shaft so as to be integrally rotatable with the shaft, and a slider that is attached to the rotor and alternately slidably contacts the insulator portion and the resistor portion by rotation of the shaft. The insulator portion includes a base material made of a resin, spherical silica, and a fluororesin filler.

A disconnector that includes at least two modular contact boxes, each one having a box-like body coupled to a contiguous box-like body of a contiguous modular contact box. Each box-like body defines a seat that accommodates a moving contact and two peripheral seats, each of which accommodates a corresponding fixed contact that can be accessed from outside the modular contact box. The at least two box-like bodies include at least one first box-like body, in which at least the outward-facing surface has a first finish, and at least one second box-like body, in which at least the outward-facing surface has a second finish, the contacts of the first box-like body or bodies having one polarity and the fixed contacts of the second box-like body or bodies having an opposite polarity.
