Product Details
Product Overview
Specification：The ZD18-22A series push button switches feature diverse and beautiful styles, easy and secure installation, and reliable and stable operation. They are available in three standard mounting hole diameters: medium 22mm, medium 25mm, and medium 30mm, encompassing a wide range of applications.
Performance：Made of high-quality engineering flame-retardant materials, it has good insulation performance, reliable contact, and is resistant to vibration and impact. The product complies with IEC60947-5-1, GB14048.5 and other standards.
Structure：The switch elements have two structures: "slow action" and "fast action" with "self-cleaning" function; the switch seats can be assembled in a building block style. Each switch seat can be installed with 2 switch elements, and up to 8 switch elements can be combined as required to meet the requirements of various specific control circuits.
Protection level：The protection level is IP40, and some products can reach IP65 or IP67
