A steering apparatus for a game machine according to the invention has a mechanism in which a steering wheel is rotated in accordance with the steering operation of the player and is automatically returned to the center. An end cam which always receives the elastic force of a compression coil spring sets the steering wheel to the neutral position, namely, the center by way of a guide roller. For instance, when the player operates the steering wheel to the right rotational direction, the guide roller rotates to the right together with the steering shaft. Thus, the end cam moves along the axial direction of the steering shaft in accordance with a rotational angle of the steering wheel. Then, when the steering wheel is released, the end cam receives the elastic force of the compression coil spring and allows the steering wheel to be returned to the center by way of the guide roller without performing the reversing operation of the steering wheel.In the apparatus of the invention, a detector of the rotational angle and rotational direction of the steering shaft is provided and an automobile displayed on the display is operated.

A snap action switch including a switch in incipient form. The switch comprises a contact having a cut-out tongue mounted on a post with the tongue bent to form a spring, the post being one terminal. The other end of the element remote from the tongue end initially contacts an exposed second or third terminal above or below the other end. When an actuator or nose from a resilient body acts against the surround adjacent the tongue end, force is exerted against the contact. The contact snaps from the initial connection between the nose and one of the second or third contacts to the other. When the resilient body relaxes, the nose resumes its original position and the switch snaps back to resume a connection between the post and the initial connection with the second or third terminal.

A unitized manual actuator assembly is attached to a printed circuit board for operating poppet switches mounted thereon. The actuator assembly comprises a two-piece housing having a pair of integral tube guides disposed in the housing. A pin is slideably disposed in each tube guide with one end protruding out of the housing for operating the switches. The internal end of each pin has an integral hollow cap covering and protecting the upper open end of its associated tube guide. A coil spring surrounds each tube guide and engages the integral hollow cap of the pin to bias it against a rocker member pivotally mounted in the housing. The rocker member has an operator portion extending through an opening in the housing and a pair of oppositely extending arms engaged by the hollow caps so that the pins translate in opposite directions when the rocker member is pivoted.

A keyboard assembly comprises a base, a plurality of pressure-operated switches mounted on said base, a keyboard comprising support means overlying the switches and having a plurality of key locations formed therewith, each including a key hinged at one side to the support means and disposed in operative relation to one of the switches, the support means defining a first aperture in each key location to permit movement of the key therethrough, each of the keys including a cantilever switch actuator which is initially formed in a first position on one side of the support means and then rotated so that it extends beneath said key from a toggle hinge on one side thereof to a second aperture in each key location on an opposite side of said key, said actuator being positioned to engage the corresponding switch when the key is depressed, an enlarged end portion of said switch actuating means being received in said second aperture, and coacting therewith during key depressing movement, said switch actuating means being retained in the rotated position beneath its key by said toggle hinge.

The invention provides a multiple switch actuating mechanism for use in combination with a biased open switch unit. The multiple switch actuating mechanism includes an angle shaped member for receiving the biased open switch unit. The angle shaped member has a pivotal means secured thereto. A rocker arm is secured to the pivotal means for oscillatory motion. The rocker arm has first and second rotatably mounted switch contact bearing elements secured to the rocker arm remote from each other. This just described arrangement of rocker arm and rotatably mounted switch contact bearing elements is such that the aforementioned oscillatory motion is transmitted simultaneously to the rotatably mounted switch control bearing means. There is also provided at least one actuating handle for the mechanism and this handle is secured to the rocker arm. The rotatably mounted switch contact bearing elements provide a driving contact with respectively a first and a second biased open switch of the push button type, whereby an oscillatory force applied to the actuating handle causes the oscillatory motion to be transmitted to the first and then to the second biased open switches. This oscillatory motion is converted to unidirectional motion within the push button biased open switches.

A switching device, capable of being applied to the steering column of an autovehicle is described. The device comprises a sleeve which is provided with a front seat for housing one of the releasing pawls. The releasing pawl is capable of engaging with a shaped sector formed in an annular body operable by means of a radial lever connected to the steering wheel. The shaped sector presents a substantially concave central portion delimitated by two tooth raised portions and two nearly flat side portions. The annular body supports a resiliently biased contact plate and is provided with a cylindrical seat in which is housed a resilient pin. Near the annular body is located a disc structure on which are arranged three fixed contacts having suitably sized contacting surfaces. The fixed contacts are connected to the contact plate by slightly rotating the annular body. The device permits to avoid a double operation for each signalling maneuver.

A snow plow having a blade movable by a plurality of drive devices actuated by switch members is controllable by a stick shift having a hand grip at one end and contacts at the other end for engagement with the switch members. The stick shift is pivotal from a neutral position in a selected one of a plurality of paths into engagement with the switch members, and includes in combination with its hand grip two additional switches for controlling at least one additional operation of said blade independently of the position of the stick shift.

The present invention relates to vehicle directional signal controls for vehicles of the type steered with handle bars. The control is for electrically operated signals and is selfcancelling. The entire control and switch mechanism is mounted within the handlebar and includes a plurality of cams, one of which is spring loaded and floats. Twisting of the handlebar grip connects the electrical power source to the proper signal which is automatically cancelled upon release of the grip.

An electric switch in the shape of a knob arranged for mounting on the end of a mechanical control lever, the knob being in two parts of which one is rotatable to perform an electrical switching function. The switch is preferably spring biassed to a ''normal'' position by a compression spring lying between the two parts.
