The **W2TS-N22-R** belongs to the **W2TS Series** of subminiature, water-resistant basic switches (microswitches), commonly manufactured by brands like **Omron**. These switches are designed for high reliability in harsh environments where moisture or dust is present. --- ## 1. Technical Specifications Below is a breakdown of the core electronic and mechanical characteristics of the W2TS-N22-R. | Parameter | Specification | | :--- | :--- | | **Switch Type** | Subminiature Basic Switch | | **Actuator Type** | Hinge Lever | | **Contact Form** | SPST-NO (Single Pole Single Throw - Normally Open) | | **Current Rating** | 100mA at 30VDC (Logic level load) | | **Protection Rating** | Equivalent to IP67 (Waterproof/Dust-tight) | | **Operating Force** | ~1.5 N (Newton) | | **Terminal Type** | PCB Terminals (Right-angled or Straight depending on suffix) | --- ## 2. Key Electronic Components & Features ### A. Contact Mechanism The "N22" designation typically refers to the contact arrangement and force. In this specific series: * **Crossbar Contacts:** It usually employs gold-alloy crossbar contacts, which are essential for **low-load switching** (electronic circuits) to ensure high contact reliability and prevent oxidation. * **Normally Open (NO):** The circuit remains open until the lever is depressed. ### B. Environmental Sealing * **Molded Lead Wires/Epoxy Sealing:** The base of the switch is often sealed with epoxy resin to prevent liquids from entering through the terminals. * **Internal Rubber Boot:** A flexible internal seal protects the internal mechanical plunger from water ingress, making it suitable for automotive or outdoor appliances. ### C. Mechanical Interface * **Hinge Lever:** The "-R" suffix often denotes the specific lever shape or orientation. The hinge lever reduces the force required to actuate the switch compared to a pin plunger, allowing for detection of moving parts over a wider area. --- ## 3. Common Applications Due to its small footprint and waterproof nature, the W2TS-N22-R is used in: 1. **Automotive:** Door latch detection, seatbelt buckles, and hood sensors. 2. **Appliances:** Water level detection in washing machines or coffee makers. 3. **Industrial:** Limit switching in pneumatic cylinders or outdoor security gates. --- ## 4. Pinout Logic Most switches in this series follow a standard subminiature footprint: ```text [ Lever ] _______|_______ | | | (Body) | |_______________| | (1) | (2) COM N.O. ``` *(Note: As an SPST-NO switch, it only utilizes two active terminals.)*
