Description

Technical Field

[0001] The utility model relates to a special toggle switch for new energy vehicles. Background Art

[0002] A toggle switch for new energy vehicles is a type of switch used to control vehicle interior and exterior functions such as lights, wipers, air conditioning, and seat adjustment. The switch is opened and closed, and the function is switched, by toggling a control lever. A typical toggle switch consists of a switch housing, a switch base, a switch lever, a drive block, conductive silicone, and a circuit board. The switch lever moves, causing the drive block to press the conductive silicone, connecting the circuit board signal. Frequent use of existing toggle switches has revealed the following issues, according to user feedback: 1. The switch lever is prone to shifting during toggle operation, causing the pressing position to deviate, reducing the reliability of the operation; 2. The conductive silicone is prone to misalignment and difficulty resetting after frequent pressing, posing a risk of poor contact. Improvements and optimizations are being implemented to address these issues. Utility Model Content
