SPDT Momentary Switch: Definition & Core Functions

Product Definition

The SPDT Momentary Switch is a switch with single pole double throw (SPDT) structure, featuring three terminals: common (C), normally open (NO), and normally closed (NC). Designed for momentary operation, it returns to its original state when released. Equipped with a matched socket, the switch ensures easy installation. Its quick-action design provides self-cleaning contact points for stable operation and long service life.

Core Applications

The SPDT Momentary Switch is commonly used in console panels, control cabinets, distribution boxes, instrument boxes, and mechanical control systems. It supports signal control, power control, circuit reversing, and temporary operation scenarios.

FAQ (Frequently Asked Questions)

• Q1: What is the difference between SPDT Momentary Switch and latching switch?
  A1: The momentary switch only maintains state when pressed and returns after release; a latching switch keeps the state until pressed again. Momentary is ideal for temporary control scenarios.
• Q2: Can the switch be customized?
  A2: Yes. Yijia supports OEM/ODM customization including protection level, shell material, contact structure, LED voltage/color, custom symbols, etc.
• Q3: Are free samples available?
  A3: Yes. Yijia has stock and provides free samples for testing.
• Q4: What certifications does it have?
  A4: CCC, TUV, CE, RoHS, and optionally Reach, compliant with global standards.
• Q5: How to select the appropriate SPDT Momentary Switch?
  A5: Provide mounting hole size, load current, head type, contact structure, LED voltage/color, shell material, and special requirements; Yijia will recommend the right type.
