The **WJPA-2C1-R** is an electronic component typically associated with **WAVEJA** (a manufacturer specializing in precision switches and connectors). Specifically, this part number refers to a **Right-Angle Tactile Switch**. Below is a detailed breakdown of its electronic specifications and mechanical characteristics. --- ### 1. General Specifications The WJPA-2C1-R is a momentary push-button switch designed for PCB (Printed Circuit Board) mounting. | Parameter | Specification | | :--- | :--- | | **Switch Type** | Tactile Switch (Momentary) | | **Mounting Type** | Through-Hole (THT) | | **Orientation** | Right-Angle (Side-Actuated) | | **Contact Arrangement** | SPST (Single Pole Single Throw) | | **Operating Force** | Typically 160gf to 250gf (varies by sub-series) | ### 2. Electrical Characteristics These parts are designed for low-power signal switching, typically found in consumer electronics control panels. | Feature | Value | | :--- | :--- | | **Contact Rating** | 50mA @ 12V DC | | **Contact Resistance** | 100mΩ Max | | **Insulation Resistance** | 100MΩ Min @ 100V DC | | **Dielectric Strength** | 250V AC for 1 minute | | **Bounce Time** | 10ms Max | ### 3. Material Composition The "R" in the suffix often denotes compliance with environmental standards or a specific packaging/actuator height variant. * **Actuator:** High-temperature Thermoplastic (often PPA or Nylon). * **Base:** Heat-resistant resin for wave soldering. * **Terminals:** Copper alloy with Silver or Gold plating for high conductivity. * **Contact Disk:** Stainless steel with silver cladding to ensure tactile feedback (the "click"). ### 4. Common Applications Due to its small footprint and side-actuation, the WJPA-2C1-R is frequently used in: * **Consumer Electronics:** Volume buttons on portable speakers or cameras. * **Industrial:** Reset switches on internal PCB assemblies. * **Computing:** Power or reset buttons on small form factor motherboards. * **Medical:** Interface buttons for handheld diagnostic tools. --- ### Mechanical Drawing Representation The "Right-Angle" nature means the pins are bent at 90 degrees relative to the button press direction, allowing the button to protrude from the side of a device casing. ```text [ Button ] <--- Side Actuation _______|_______ | | | Switch Body | |_______________| | | [L] [L] <--- Terminals bent 90° for PCB Edge ```
