The **KAN-R** is a specific series of **rocker switches** commonly used in small household appliances, power tools, and industrial equipment. These switches are known for their compact size and reliable mechanical action. --- ### 1. Technical Specifications The electrical characteristics of a KAN-R switch typically fall within the following parameters: | Parameter | Typical Value | | :--- | :--- | | **Current/Voltage Rating** | 6A 250V AC / 10A 125V AC | | **Contact Resistance** | ≤ 50mΩ | | **Insulation Resistance** | ≥ 100MΩ (500V DC) | | **Dielectric Strength** | 1500V AC / 1 minute | | **Electrical Life** | ≥ 10,000 Cycles | | **Operating Temperature** | -25°C to +85°C | --- ### 2. Physical Construction A KAN-R switch consists of several key electronic and mechanical components: * **Housing (Body):** Usually made of UL94V-2 rated Polyamide (Nylon 66), which provides high heat resistance and electrical insulation. * **Actuator (Button):** The rocker mechanism that the user presses. * **Terminals:** Usually silver-plated brass or copper. These are available in different styles: * **Solder Lugs:** For direct wire soldering. * **Quick Connect:** Tab-style (e.g., 4.8mm) for push-on connectors. * **PCB Pins:** For direct mounting onto a circuit board. * **Contacts:** The internal moving parts (often silver alloy) that bridge the circuit to allow current flow. --- ### 3. Circuit Configurations The "KAN-R" designation usually refers to the form factor, but the internal wiring can vary. The most common types are: 1. **SPST (Single Pole Single Throw):** Simple ON-OFF (2 pins). 2. **SPDT (Single Pole Double Throw):** ON-ON or ON-OFF-ON (3 pins). 3. **Illuminated:** Some versions include a built-in **Neon lamp** or **LED** to indicate when the switch is in the "ON" position. These require a neutral wire connection to power the internal light. --- ### 4. Typical Applications Because of its small footprint and moderate current handling, the KAN-R is frequently found in: * Water dispensers and coffee makers. * Computer power supplies (PSUs). * Power strips and surge protectors. * Vacuum cleaners and hair dryers.
