The term "dz kw 3" appears to be a partial and likely misspelled reference to a type of micro switch, such as a KW3 or KW10 series switch. These switches are frequently used in computer mice and other small electronics.

The PRR2 102 NI is a round, non-illuminated, single-pole, ON/OFF rocker switch. It has a panel cut-out of 20.2 mm and push-on/solder terminals. It is rated for 10A, 250V AC. 

Fan regulators are devices that help control or regulate the speed of fans. Installed with a circular knob, they directly control the speed with which the ceiling fan's motor rotates. Usually, they are a part of the switchboard or can also be installed as a separate device.

A KW-10 4-pin mouse micro switch is a subminiature, momentary contact switch with a specific wiring redundancy. The KW-10 series is commonly used in computer mice and a variety of other electronics. The 4-pin configuration is an adaptation of the standard 3-pin Single-Pole, Double-Throw (SPDT) switch, where pairs of pins are internally connected to offer redundant connection points.

A 6-pin deck power switch is typically a Double Pole Double Throw (DPDT) switch used to control two separate electrical circuits or a single circuit with reversible polarity. The "deck" part of the name refers to its common use in marine applications, though these switches are used in many different electrical projects, including cars, robots, and appliances.

A "12 pin deck power switch" is a general term for a switch with 12 connection pins, often referring to different electronic components depending on the specific application. The most common contexts where you might encounter a 12-pin "deck" or PCB switch are in gaming hardware and custom electronics projects.

A Single-Pole Double-Throw (SPDT) Center-Off Switch is a type of electrical switch commonly used in electronic circuits and control applications where a user needs to choose between two outputs or directions — or switch off the circuit entirely. The “center-off” designation means that the switch has three positions: one connecting the pole to one throw, one connecting it to the other, and a central neutral or “off” position where no connection is made.

• SPDT: A switch that has one input (pole) and two outputs (throws). It can connect the input to either output.

• Center-Off: A variation where the switch has three stable positions:

  • Position 1: Pole connected to Throw A.

  • Position 2: Pole connected to Throw B.

  • Center (neutral): No connection — the switch is off.

This design allows for bidirectional control with an “off” state in between, which is extremely useful in applications such as motor control, selector circuits, and manual overrides.

In schematic diagrams, a SPDT Center-Off Switch is typically drawn as:

• In Position A, the common terminal (pole) connects to Throw A.

• In Position B, it connects to Throw B.

• In the center-off position, the common terminal is disconnected from both throws.

• Pole terminal: The movable contact (often at the bottom).

• Throw terminals (A and B): Stationary contacts.

• Actuator: The toggle, slide, or rocker that changes the switch position.

• Housing: The casing that holds the internal mechanism.

• Toggle Switch: Flips up, center, or down.

• Slide Switch: Slides left, center, or right.

• Rocker Switch: Rocks to left or right with center-off.

• Pushbutton (spring-return center-off): Returns to center automatically.

SPDT Center-Off Switches are widely used in applications requiring reversible operations or selection between two modes with a neutral state:

• Common in DC motor control, where:

  • One throw drives the motor forward.

  • The other drives it in reverse.

  • The center-off stops the motor.

• Used to toggle between two lighting circuits or brightness levels with an off state.

• Selects between two input sources or outputs, or disconnects entirely.

• Switches direction of motors or track voltage.

• Allows momentary or latching control between two states and a neutral.

• Rated by maximum voltage and current it can safely handle.

• Choose a switch that matches or exceeds your circuit’s demands.

A "Deck power switch 24 pin" most likely refers to a specialized accessory used for powering on a computer's ATX power supply unit (PSU) without it being connected to a motherboard. The "deck" part of the name refers to the component being used on a "test bench" or deck-like setup for standalone testing, rather than a normal PC case

A “tactile switch” is a widely used switch that completes an electrical circuit when pressure is applied to the device by the user, which then gives the user a perceptible “click” or haptic bump in response, indicating current flow. Current flow is turned off when the switch is released.

The SPST MKA-14103 reed switch is a miniature, single-pole, single-throw, normally open (NO) magnetic switch sealed in a glass tube. When a magnetic field is applied, the two ferrous reeds inside the capsule pull together, completing a circuit. It is a durable and reliable component used in various low-power applications.

A slide switch is a mechanical switch that operates by moving a slider or handle in a linear motion to open or close an electrical circuit. They are known for providing clear visual and tactile feedback on their on/off or multi-position state. Slide switches are commonly used in various electronics due to their compact size and simple, reliable functionality. 

A joystick is an input device consisting of a stick that pivots on a base to control the movement or actions of a digital object. While commonly used for gaming, joysticks also have applications in industrial controls, robotics, and assistive technology

A key lock rotary switch is a type of electrical component that combines a rotating selector switch with a key-operated locking mechanism. It requires a physical key to change positions, preventing unauthorized or accidental operation of the equipment it controls. 

A key lock switch is an electrical switch operated by a key, offering a higher level of security than standard switches. They are designed to prevent unauthorized or accidental operation of equipment. They are commonly used in industrial machinery, control panels, elevators, security systems, and ignition systems for vehicles. 

While "deck power switch 18 pin" returns results for various electronic components, the most common association is the 18-pin power switch ribbon cable found inside the Valve Steam DeckIf you are looking for information about the power button, power cable, or a replacement part for a Steam Deck, this is the most likely context
