single pole automotive switch type

As a professional automotive micro switch manufacturer, our Single Pole Automotive Switch is designed for automotive electrical systems, including IP67 waterproof switches, subminiature micro switches, snap action switches, SPDT micro switches, etc. This series of switches uses high conductivity materials with high-temperature resistant engineering plastic housings, and operates stably between -45°C~+85°C. According to different automotive application requirements, it can be divided into the following types of Single Pole Automotive Switch.

single pole automotive switch circuit

Single pole automotive switches generally have two types of circuit switches, SPST (single pole single throw) automotive switches and SPDT (single pole double throw) automotive switches. The circuit is shown in the circuit diagram on the right.
SPST
The SPST switch is the most basic circuit control switch with one input (single pole) and one output (single throw). It functions like an "on/off" button - when the switch is closed, the circuit is turned on; when the switch is open, the circuit is turned off.
SPDT
The SPDT switch also has only one input (single pole), but two outputs (double throw). It can switch the circuit from one output to another, realizing a dual-path control function. For example, it can switch from a red light to a green light, instead of simply controlling the switch on and off like the SPST.

Application of single pole automotive switch in automobiles

The lights of the car sun visor use the Unionwell G3 series SPDT automotive switches. The sealed micro switch is mainly used to detect the opening and closing status of the sun visor. When the driver or passenger opens the sun visor, the micro switch is triggered, and then the mirror light hidden on the back of the sun visor is automatically lit; when the sun visor is closed, the light automatically turns off. This automatic sensing improves user convenience and usage experience.

    Another one is the car door lock control. The micro switch is linked to the internal machinery. When the car door fails to close normally, the micro switch activates and sends a signal to the central system to prompt the driver to check the door lock. This operation mainly uses the Unionwell G10 SPDT subminiature micro switch, which has SPDT circuit, small size, reliability and durability, and is widely used in door switches of multiple brands.
