A switch in particular for a master cylinder unit, for opening and/or closing an electrical circuit, for example, for switching on the brake lights, comprises a casing suitable for being housed in a compartment of the cylinder body, a first electrical contact fixed firmly to the casing, a movable element slidable in the casing, a second electrical contact associated with the movable element, and a resilient element for keeping the movable element constantly urged against the piston of the master...

A switch is provided, which is stable in operating characteristics and can be operated with a small operating force, and which is long in life and easy to manufacture. The switch includes a base, a moving contact piece having one end thereof supported pivotally on the base, an operating lever supported pivotally on the base and having a drive part pushing a coil portion of the moving contact piece, and a cover having a planar shape capable of covering the base and fixed to the base to compress t...

A switch having two planes opposing and substantially in parallel to each other and switching between a first electrode and another electrode by pressing down one of the planes. Contact point patterns each made of a conductive material having a specified shape are provided on one of the planes. Stripe electrode patterns in which the first electrode and the other electrode are alternately positioned are provided on the other plane in a region where the contact pattern on the one plane is superimp...

A switch (10) with a mass (17) which moves along a path (32) between a home position and at least one switching position displaying at least a first reset element (18), which prestresses the mass (17) in its home position, and a switching contact (27) activated by the mass (17). The first reset element (18) comprises an actuating part (15) which actuates the switching contact(27) when the mass (17) moves against the force of the first reset element (18) from its home position towards its at leas...

A switch having a long contact life is provided. A neutral contact blade is provided with a first neutral contact and a second neutral contact. A primary movable contact blade and a secondary movable contact blade are supported by these first and second neutral contacts, respectively, for seesaw motion. The operation of a lever causes the primary movable contact blade and the secondary movable contact blade through a pushrod to move in a seesaw motion in such a manner that a secondary movable co...

A switch includes a first member, one end of which being secured to a substrate, multiple first beam portions respectively having multiple first contact portions, one ends of the multiple beam portions being secured to the first member, multiple contact switch portions connected in parallel, the multiple first contact portions and multiple second contact portions being in a contact state or in a non-contact state in the multiple contact switch portions, and resistors arranged respectively betwee...

A switch comprises a housing having an upper member and a lower member, an actuator disposed in the housing and rockably supported on the upper member, switch means for connecting and disconnecting a movable contact with a stationary contact when the actuator rocks on the upper portion, and a connecting terminal for an external electric wire electrically connected to the switch means. The switch means includes a movable contact element having the movable contact and a support element which rocka...

A switch which is superior in current limiting performance. The switch comprises a movable contact element having a pair of movable contacts secured thereto, a pair of fixed contacts individually secured to fixed contact elements for individually contacting with the movable contacts, an electromagnetic driving device including a movable iron core, and a first operating rod secured to the movable iron core. An electromagnet is disposed alongside the electromagnetic driving device and includes a m...

A switch capable of significantly reducing the number of parts therefor and permitting the manufacturing and assembling to be carried out with high efficiency. Only four parts consisting of a casing, a top plate or a bottom plate, a cam lever and a leaf spring each simplified in structure are required to construct the switch. The cam lever causes pressing force acting in a small magnitude on its lever section to be changed to pressing force of an increased magnitude acting on its cam section in ...

A push-button rachet mechanism switch is converted to a rotary wiping action for a moveable contact which includes one or more axial extending contact members. The moveable contact selectively engages one or more radially spaced fixed contacts and continuously engages a common conductor for selectively coupling the common conductor to one or more of the radially spaced fixed contacts to which other conductors are coupled.
