SPDT micro switch explanation

SPDT micro switch can control circuit switching, switching between normally open (NO) and normally closed (NC) terminals, and realize precise switch control (the structure diagram is shown in the figure). In addition, the following are the characteristics of SPST switch and DPDT switch:
SPST Micro Switch:
SPST (single pole single throw) micro switch only controls the on and off of a single circuit. It has a simple structure and stable operation. It is widely used in applications that require basic switch control, such as home appliances and security equipment.
DPST Micro Switch:
The DPST micro switch has a double-pole single-throw (DPST) structure, which can control the on and off of two independent circuits at the same time to achieve synchronous switching. It is suitable for dual power supply control and circuit isolation applications.
DPDT Micro Switch:
DPDT (double pole double throw) micro switch can control the switching of two sets of circuits at the same time. It has more complex control functions and is suitable for multi-channel circuit applications such as automation equipment, industrial control and communication equipment.
