[Product Overview] Single-row 3-pin two-position straight-terminal mini toggle switch with nut (SPDT single-pole double-throw / panel locking mount / threaded bushing with hex nut / cylindrical lever / through-hole solder pin terminals)

Single-row two-position straight-terminal mini toggle switch with nut (Threaded Bushing Panel Mount Toggle Switch SPDT 3 Pin Straight Terminals) is a product specifically designed for Equipment enclosure panel mounting, chassis control consoles, instrumentation, and high-reliability circuit boards A panel-locking lever control switch crafted for these applications.

Standard single-row 3-pin straight leads combined with a classic Precision threaded metal bushing + hex locking nut/lock washer + cylindrical metal lever + SPDT (ON-ON) circuit , with the following core advantages:

• Panel locking nut fixation (pull-out resistant and anti-loosening)Equipped with a standard threaded metal bushing and matching hex nut and washer, it can be securely locked through the equipment panel opening. External forces are absorbed by the cabinet panel, greatly protecting internal PCB solder joints from being pulled or damaged.
• Single-row 3-pin straight terminals (Straight Pins): The pins are arranged in a straight vertical through-hole configuration, supporting both direct insertion into PCB motherboards for soldering and flying-wire soldering with leads, offering exceptional versatility.
• High-quality silver-plated terminals and contactsThe terminals and internal contact points undergo precision silver plating, resulting in extremely low contact resistance, excellent oxidation resistance, and smooth solder wetting during both wave soldering and manual soldering.
• Classic cylindrical metal toggle lever (crisp tactile feel)Pressing and toggling provide a clear, natural tactile response, with crisp and decisive position switching without hesitation. The metal lever's surface coating resists corrosion and delivers extremely high mechanical durability.
• Single-pole double-throw (SPDT ON-ON) precise switching: Features a minimalist and efficient structure with two stable positions; toggling the handle smoothly switches the common terminal (COM) between the other two terminals.
• High-insulation, heat-resistant housing with long-life design: Adopts a high-quality red/black engineering insulating plastic base and anti-corrosion metal top cover, with high flame retardancy rating, excellent temperature resistance, and a mechanical switching life of over 50,000 cycles.
