FAQ
What is a SPDT momentary micro switch?
A SPDT (single pole double throw) momentary micro switch is a mechanical switch with three terminals (COM, NO, NC). When the switch is pressed, the circuit switches from one path to another, but once released, the contacts automatically return to their original state. This switch is suitable for short-term trigger signals or fast switching circuits.
How does an SPDT momentary micro switch work?
The SPDT momentary micro switch has a metal dome structure inside. When the switch is pressed, the dome quickly switches the contacts, causing the common end (COM) to jump from the normally closed (NC) end to the normally open (NO) end. Once the button is released, the dome returns to its original position and COM reconnects to NC. This design gives the switch the characteristics of fast response and short switching.
Is the SPDT momentary micro switch normally open or normally closed?
What are the application scenarios of SPDT momentary micro switches?
What are the common faults and causes of SPDT momentary micro switches?
Contact burnout – Due to long-term high current or frequent switching operations, the contact surface is oxidized or melted, resulting in poor contact or failure.
Mechanical jamming – The internal springs are aged, deformed or dusty, resulting in failure to reset or slow response after pressing.
Regular inspection and reasonable selection of high-quality SPDT momentary micro switches that meet current and voltage specifications can effectively reduce the occurrence of faults.
