The rubber pad material has good shock absorption and sound absorption properties, which can reduce the noise generated during the operation of the equipment and improve the comfort of the operating environment. It effectively reduces the damage to the equipment caused by vibration and impact, and prolongs the service life of the pressure switch and its internal components.

[0019] 4. The reinforcing rib structure includes a plurality of strip ribs, which are evenly arranged on the outer wall of the protective shell, and each strip rib is fixed to the protective shell. The strip ribs can significantly enhance the structural strength and rigidity of the protective shell, and increase the overall durability of the pressure switch. The existence of the reinforcing ribs enables the protective shell to better disperse and absorb the impact force when it is subjected to external impact, and protect the internal components from damage. The reinforcing ribs can effectively prevent the protective shell from deforming during long-term use or in harsh environments, and maintain the appearance and function of the equipment stable. The enhanced structural strength and stability make the equipment less likely to be damaged during installation and maintenance, and improve the convenience and safety of operation.
