The **17AC-AB6-R** is a specific electronic component primarily identified as a **tactile switch** (or tact switch) commonly used in consumer electronics, automotive controls, and industrial interfaces. Below is a detailed breakdown of its specifications and characteristics. --- ### 1. General Specifications The 17AC series typically refers to a standard sized, through-hole or surface-mount momentary switch. | Parameter | Typical Value / Description | | :--- | :--- | | **Component Type** | Tactile Switch | | **Circuitry** | SPST - NO (Single Pole Single Throw - Normally Open) | | **Actuation Force** | 160gf to 260gf (varies by sub-model) | | **Current Rating** | 50mA | | **Voltage Rating** | 12V DC | | **Mounting Type** | Through-Hole (R-Suffix often denotes specific orientation/packaging) | | **Travel Distance** | ~0.25mm | --- ### 2. Physical Characteristics The "AB6" portion of the part number usually dictates the physical dimensions and the height of the plunger (actuator). * **Size:** Generally follows a 6x6mm footprint. * **Height:** The "6" often indicates a 6mm height from the base to the top of the plunger. * **Terminals:** Usually features 4 pins. Internally, pins are connected in pairs, and pressing the button closes the circuit between the two pairs. * **Feedback:** Provides a distinct "click" sound and haptic feel when pressed. --- ### 3. Pin Configuration and Operation Since it is an SPST-NO switch, its operation is simple: 1. **Rest State:** The circuit is open; no current flows. 2. **Pressed State:** The internal metal dome collapses, connecting the terminals. 3. **Released State:** The dome springs back, breaking the connection. --- ### 4. Common Applications Due to its reliability and low cost, the 17AC-AB6-R is used in: * **Computer Peripherals:** Reset buttons, power buttons. * **Household Appliances:** Microwave control panels, washing machine interfaces. * **Development Boards:** Common on Arduino and Raspberry Pi shield kits. * **Industrial:** Input keys for PLC (Programmable Logic Controller) interfaces. --- ### 5. Part Number Decoding (Typical) * **17AC:** Series designation (Manufacturer specific). * **AB:** Style/Housing type. * **6:** Height (6mm). * **R:** Often denotes **RoHS Compliance** or **Tape & Reel** packaging.
