The **10SP-2E6-R** is a specific part number belonging to a series of **Tactile Switches** (Pushbuttons), typically manufactured by companies like **Mountain Switch** or **Mouser/Alpha**. These are commonly used on Printed Circuit Boards (PCBs) for user input. ### Technical Specifications | Parameter | Specification | | :--- | :--- | | **Switch Type** | Tactile / Momentary Pushbutton | | **Circuit Configuration** | SPDT (Single Pole Double Throw) | | **Switching Function** | On-Mom (Momentary On) | | **Contact Rating** | 0.4VA max @ 20V AC or DC | | **Mounting Type** | Through-hole (PCB Mount) | | **Termination Style** | PC Pin | | **Actuator Style** | Round / Plunger | | **Environmental** | RoHS Compliant | --- ### Key Features and Component Breakdown #### 1. SPDT Configuration Unlike standard "on/off" switches, this part is **Single Pole Double Throw**. This means it has one common pin that can toggle between two separate output pins. In a momentary state, it defaults to one position and switches to the second only while the button is held down. #### 2. Gold Contacts (Logic Level) The "0.4VA" rating indicates that this switch is designed for **low-power logic levels**. It typically features gold-plated contacts to ensure high reliability when switching very small currents (dry circuits) where oxidation could otherwise cause failure. #### 3. Mechanical Design * **Momentary Action:** The switch returns to its original position as soon as physical pressure is removed. * **Right Angle or Straight:** Depending on the specific suffix, these are often available in vertical or right-angle configurations for edge-mounting on a PCB. * **Durability:** Usually rated for 30,000 to 100,000 electrical cycles. --- ### Common Applications * **Consumer Electronics:** Reset buttons or mode selection. * **Industrial Controls:** Low-power signal switching on control panels. * **Medical Equipment:** Interface buttons for handheld diagnostic tools. * **Telecommunications:** Configuration toggles on networking hardware.
