The **M2TS-7A-R/UL** is a high-performance, miniature slide switch typically used in industrial and telecommunications equipment. It is manufactured by **Nidec Components (formerly Copal Electronics)**. --- ## 1. Technical Specifications The following table outlines the key electronic and mechanical characteristics of the M2TS series: | Property | Specification | | :--- | :--- | | **Switch Function** | DPDT (Double Pole Double Throw) | | **Circuit Configuration** | ON-ON | | **Current Rating** | 6A @ 125VAC / 3A @ 250VAC | | **Contact Resistance** | 20 mΩ Max | | **Insulation Resistance** | 1,000 MΩ Min (500VDC) | | **Dielectric Strength** | 1,500 VAC for 1 minute | | **Mechanical Life** | 50,000 Cycles | | **Operating Force** | 0.98 ~ 4.9 N | --- ## 2. Component Composition The part is constructed using high-grade materials to ensure reliability under thermal stress: ### A. Contact Material * **Silver Contacts:** The "R" in the suffix usually denotes silver-plated contacts, which are ideal for power applications due to their low resistance and high conductivity. ### B. Terminal Style * **Solder Lug Terminals:** These are designed for manual wiring or wire-wrap applications. They are robust and resistant to vibration. ### C. Housing & Actuator * **UL 94V-0 Rated:** The "UL" suffix indicates that the plastic components (housing and base) are certified under Underwriters Laboratories standards for flame retardancy. * **Internal Mechanism:** Uses a "twin-contact" or sliding contact mechanism to ensure a "self-cleaning" effect every time the switch is toggled. --- ## 3. Pinout & Logic As a **DPDT (Double Pole Double Throw)** switch, it controls two independent circuits simultaneously. ```text Terminal Layout (Bottom View) [ 1 ] [ 4 ] <-- Pole A / Pole B [ 2 ] [ 5 ] <-- Common A / Common B [ 3 ] [ 6 ] <-- Pole A / Pole B ``` * **Position 1:** Pin 2 connects to Pin 1; Pin 5 connects to Pin 4. * **Position 2:** Pin 2 connects to Pin 3; Pin 5 connects to Pin 6. --- ## 4. Typical Applications * **Industrial Control:** Used as a power or mode selector switch in heavy machinery. * **Telecommunications:** Used for signal routing in rack-mounted hardware. * **Medical Equipment:** Reliable switching for diagnostic tools requiring UL safety certification.
