SMA2 Piezo Switch
The SMA2 from Everswitch is a 22.5mm non-illuminated metal touch piezo switch with a recessed face which is engineered for ultimate durability and performance, whilst providing protection against moisture and dust.
Opposed to the SMA1, the SMA2 has a recessed face offering a more tactile experience while still offering a lifespan of 50 million operations. The SMA2 provides a trustworthy answer to your control panel demands even in the harshest conditions, with a rating of IP69. It is an ideal choice across a wide range of applications in various industries, like spas and swimming pools, among others, where harsh environments call for the highest level of resistance.
This switch is also customisable, available in Aviation Grade Aluminium or Stainless Steel 303, with optional variants in Stainless Steel 304 or 316, ensuring maximum durability and reliability. This switch can also be anodized to have a silver, black, red, green, blue or gold finish. Laser engraving or anodized printing is also available, meaning it’s easy to adapt the switch to your needs.
