MTS402 Red 6 mm Toggle Switch - Key benefit: Compact, visible control for panel-mounted circuits. The 6 mm red toggle is easy to identify and operate in tight spaces. - Function and specs: 12-pin connector with a latching action that supports 2- or 3-position operation. Offers flexible wiring options for multi-circuit setups. - Why you need it: Use when you need a compact, clearly visible switch with stable latching positions and multiple pin connections for complex or multi-path circuits. MTS403 SPDT ON–OFF–ON Toggle Switch - Key benefit: Simple, reliable single-pole double-throw control with a center off position for straightforward circuit routing. - Function and specs: SPDT configuration with ON–OFF–ON positions for easy selection between two outputs or isolation. - Why you need it: Ideal when you need to toggle power or signals between two circuits, or provide a neutral center-off state with a robust mechanical action. Waterproof Cap (MTS403, One Size) - Key benefit: Protects the MTS403 toggle from moisture, dust, and accidental actuation in damp or outdoor environments. - Compatibility: One size designed specifically for the MTS403 switch. - Why you need it: Extends service life and reliability of the MTS403 in harsh conditions without changing the switch or panel cutout. Common features and what makes these switches stand out - Toggle design: Positive tactile feedback and clear position indication for reliable manual control. - Pin configuration: 12-pin layout on the MTS402 enables complex wiring and multi-connection solutions; MTS403’s SPDT wiring simplifies circuit routing. - Position settings: Latching 2/3-position on MTS402 and ON–OFF–ON on MTS403 give straightforward control options for many applications. - Practical performance: Mechanical latching and SPDT action provide predictable, durable switching behavior over repeated use. Practical use scenarios - Control panels and instrument clusters: Use MTS402 where compact, multi-pin control is required; use MTS403 to switch between functions or isolate circuits. - Automotive or marine auxiliary circuits: MTS403 plus the waterproof cap protects the switch while giving ON–OFF–ON control for lights, pumps, or accessories. - DIY electronics and prototyping: MTS402’s 12-pin layout supports experimenting with multiple connections and 2- or 3-position logic without changing hardware. Installation and compatibility notes - Mounting: MTS402 specified as 6 mm toggle; ensure panel cutout and clearance accommodate this size. - Wiring: Follow your wiring diagram for the 12-pin MTS402; MTS403 is SPDT — wire common, normally open, and normally closed accordingly. - Protection: Use the waterproof cap with MTS403 where moisture or contaminants are present; cap is designed for this model only. Buying considerations - Choose MTS402 when you need compact, multi-pin latching control with clear visual indication. - Choose MTS403 when you need an SPDT ON–OFF–ON arrangement and attach the waterproof cap for outdoor or wet environments. - Confirm panel dimensions and wiring requirements before installation.
