A switch for detecting a tilting operation is constructed easy to assemble. A tilt detecting section A is provided on an upper surface of an intermediate wall portionB of an upper case, a depression detecting section B is provided in a central position of an upper surface of a bottom wall portionB of a lower case, and a rotation detecting section C is provided around the depression detecting section. A top coveris provided to cover an upper end of the upper caseto which the upper caseis engageably connected. The lower caseis engageably connected to the upper case

Switch

A rotary switch section R includes a brush unitrotatably operated by a leverand a plurality of fixed contacts. The brush unitincludes a pair of main contact shoesand a single auxiliary contact shoe. The fixed contacts include a main contactwith which the main contact shoescome into contact with the leveris at its neutral posture N, a pair of contactsL,R with which the auxiliary contact shoecomes into contact first when the leveris rotatably operated, and second contactsL,R with which one of the main contact shoescomes into contact subsequently.

Combination switch

A pressure-receiving member that can be moved along an urging axial center, and a compression coil spring for urging the pressure-receiving member in the direction of an engaging body, are provided between the engaging body in an inside end position of an operating rod and a bottom wall part of a casing. A plurality of protruding pieces for restricting tilting by making contact with the pressure-receiving member is provided to the internal surface of a cylindrical part of a rotor that engages and integrally rotates with engaging pieces of the external periphery of the engaging body.

Multidirectional switch

A compound operation input device includes a casing; an operating lever accommodatable in the casing in such a manner that the lever is depressingly operable from a neutral position in a pressing-movement direction and swingingly operable from the neutral position in two opposite swinging directions intersecting the pressing-movement direction; a position detector accommodatable in the casing and adapted to output a signal in accordance with a swing of the lever; a pressing member facing an end surface of the lever on the pressing-movement direction side; and a press switch facing the pressing member with a depressible portion of the switch facing a direction substantially orthogonal to the pressing-movement direction and the swinging directions of the lever. The pressing member is adapted to move toward the switch when pressed by the end surface of the lever so as to depress the depressible portion of the switch.

Compound operation input device

In a lateral pushing type push-button switch, a pair of guiding portions against which an actuating portion that is projected from a pressing portion of an operating member into a housing is buttable are disposed in a cover which is attached to an upper portion of the housing. The switch has a second actuating member which is formed in continuously with a peripheral portion that is accommodated in a peripheral side portion of the housing, and which is projected into the housing to be opposed to the actuating portion. When the operating member is pressed in a lateral direction, the actuating portion and the second actuating member are downward displaced to depress movable contacts to be contacted with stationary contacts.

Push-button switch

Portion of a switch

A rotary type pulse switch includes a movable electrodehaving a plurality of contacting portionsA formed in positions of the same radius from its rotation center, and a fixed electrodedisposed face to face with the movable electrodeand having a plurality of contacted portionsarranged in form of stepping stones on the same circumference as a rotation locus T of the contacting portionsA. The fixed electrodeincludes a first fixed electrode patternA, a second fixed electrode patternB and a common fixed electrode pattern, each of the fixed electrode patternsA,B being in a mutually nonconductive state. The contacted portionsare arranged in such a positional relationship that a full insulation state occurs during rotation of the movable electrodein which none of the contacting portionsA contact the first fixed electrode patternA, second fixed electrode patternB or common fixed electrode pattern

Rotary type pulse switch

A main body portion has fixed contacts and houses movable contacts. A lower electrode plate and upper electrode plate serving as the movable contacts are deformed at a time of a pressing operation. The upper electrode plate is contactable to the lower electrode plate and lower electrode plate brings contact pairs mounted in a center of the bottom inside the main body portion into conduction. On the bottom inside the main body portion, contacts serving as fixed contacts for a rotating operation are formed on the circumference of the same circle outside contact pairs for the pressing operation. A brush serving as the movable contacts is secured to a lever receiving rotating operational forces and brings contacts into conduction.
