Abstract: A digital wake-up signal is generated from an analog switch on a printed circuit board in which a ground trace and multiple conductive switch traces are bridged by a moveable contactor responsive to movement of an actuator. A resistor network is coupled to the switch traces and alternatingly connects the switch traces to two outputs to generate distinct analog voltage outputs. A logic gate determines when both outputs are at the same voltage corresponding to the contactor engaged between two adjacent switch traces and generates a wake-up command signal.

Abstract: A switch comprises a case having a stationary contact embedded in an inner bottom surface thereof, a lever housed inside the case such that the lever is swingable around one end thereof, and a movable contact having an arm portion and a contact point on a first end of the arm portion, the contact point being slidable on any of the inner bottom surface of the case and the stationary contact while maintaining flexible contact therewith in response to a swinging motion of the lever. The movable contact is also provided with a holding portion at a second end of the arm portion, and the holding portion is embedded in the lever by insert molding.

Abstract: A detect switch (100) includes an insulative housing (1), a first and second fixed terminals (51, 52) retained in the insulative housing, a moveable contact (3), an operator assembly (2) and a cover (4) mounted on the insulative housing. The operator assembly (2) comprises a rotator (22) lying over the moveable contact, and an actuator (21) cooperating with the rotator (22) to drive the moveable contact. The moveable contact is formed with a pair of contacting portions (311, 321), a width of which is smaller than that of the fixed terminals. The contacting portions come to contact with and thereby electrically connect the fixed terminals when the operator assembly is manipulated.

Abstract: A digital wake-up signal is generated from an analog switch output by providing an interruption in a conductive ground or switch trace on a printed circuit board in which the ground trace and multiple conductive switch traces are bridged by a moveable contactor responsive to movement of an actuator. A resistor network is coupled to the switch traces to generate distinct analog voltage outputs when each switch trace is connected to the ground trace by the contactor. Interruption of the switch trace output and/or the ground trace changes the state of the output which defines a wake-up command.

Abstract: A lever switch includes a common contact and a fixed contact both prepared on at least an inner bottom face, or any one of inner faces of walls surrounding the inner bottom face, and a movable contact which touches or leaves at least one of the common contact or the fixed contact when a lever rotates. Terminal sections of the common contact and the fixed contact extend through walls of the housing. This structure allows the lever switch to fix those terminal sections to a wired board, thereby preventing the lever switch from coming off from the wired board. As a result, the lever switch can work with reliability.

Abstract: A microswtich that is easy to assemble and manufacture is provided. The microswitch constantly keeps the first conductive section of a resilient component for opening/closing an electrical switch in contact with the first conductive terminal in the main body of the microswitch, and houses a plate-shaped second conductive section with a contact surface inside the main body of the microswtich, so that the second conductive section of the resilient component is driven by a press button on the contact surface of the second conductive terminal to preset the signal from an initial connection state to a final connection state in order to increase the distance required for controlling the signal connection and allow the resilient component to have an effective deformation and provide the best resilience of the press button.

Abstract: An improved shock resistant auxiliary switch mechanism for a circuit breaker includes a common conductor having a conduction plate that is slidably translatable between electrically conductive contact with first and second conductors. The conduction plate is biased by a spring in a direction toward contact with the first conductor. An improved shock resistant circuit breaker including the improved auxiliary switch mechanism includes a crossbar that is operatively engageable with the conduction plate to releasably retain the conduction plate in a position in contact with the second conductor. When the circuit breaker is in an ON position, the conduction plate is operatively interposed between the crossbar and the bias of the spring.

Abstract: A switch apparatus of the invention can avoid contact damage without inviting a drastic increase in a size even when applied to a high power source voltage and does not deteriorate return feeling to a neutral state. The switch apparatus includes a switch A for cutting off connection between one side driving input of a DC motor and a negative plate side power source, a switch B for cutting off connection between the other side driving input and the negative plate side power source, and a switch C for cutting off connection between the one side driving input and the positive plate side power source and connection between the other side driving input and the positive plate side power source, wherein the switch A and the switch B are normally-closed type switches and the switch C is a normally-open type switch. The switch C is opened at a predetermined time before the switch A or the switch B is closed, and cuts off in advance a power source route to avoid the occurrence of dead short-circuit.

Abstract: A switching device includes three stationery contacts fixed to a casing and exposed on a bottom wall of casing, a conductive plate swingable about the central contact as a fulcrum and coming into contact with or detached from one of the other contacts, a drive body disposed on the conductive plate so as to be movable upwards and downwards and turnable about a shaft thereof, and a leaf spring elastically urging the shaft towards the bottom wall. The drive body has a pressing actuator protruding sidewards from the casing. When the pressing actuator is pressed by an operating knob so as to turn the drive body by a predetermined amount, a sliding actuator of the drive body slides on the conductive plate so as to turn the conductive plate. When the drive body is turned by another predetermined amount, the pressing actuator actuates a push-switch disposed near the casing.

Abstract: A double pole, double throw switching arrangement for effecting dynamic rotor braking of user controlled operation of a reversible direct current servo motor. Two columns of stationary center and oppositely disposed side contacts are disposed in spaced parallel arrangement on the switch base. One side contact in one column is connected to the opposite side contact in the other column and to the B+ supply. The remaining side contacts in each column are connected to a ground strap having a portion disposed for wiping contact. A pair of commonly user actuated moveable contact members are disposed for sliding contact with each column of contacts. The center contact in each column is connected to one end of a separate forward and reverse motor coil. In the neutral position both motor coil contacts are grounded. User movement of the common actuator in one direction simultaneously causes the moveable contact members to keep one motor coil grounded and connect the other motor coil to B+.

Abstract: An electrical switch (20) comprises a plastic base (40), a plurality of base terminals (102-112) mounted in the base, a manually pivotable actuator (200) supported for pivotal movement relative to the base, and at least one actuator terminal (260) mounted to the actuator. The actuator (200) is pivotable between a neutral position in which the actuator terminal (260) is in contact with one (106) of the base terminals (102-112) and at least one actuated position in which the actuator terminal is in contact with another (110) of the base terminals. The actuator terminal (260), when the actuator (200) is pivoted from the neutral position to the at least one actuated position, slides out of contact with the one (106) of the base terminals (102-116) and slides into contact with the other (110) of the base terminals.
