Performance All our Membrane Switch constructions are rated for durable goods exceeding 1,000,000 actuations per button (except Silicon).

Being sealed are excellent for critical environment such as rated IP65:

Explosion Proof

Medical

Transportation

Benefits● Offers antimicrobial protection

against a many bacteria including Ecoli and MRSA.

● Extensive flex life of >5 million actuations.

● Extremely durable and resistant to scratching, scuffing, chemicals and solvents.

● Excellent colour clarity when printed.

● Tough and highly durable but tactile to touch.

● Low gloss textures that are absolutely consistent across the film web.

Options Some applications require special substrates to maximize performance.

For medical applications we recommend using substrates with Microban® Technology.

On all surfaces exposed to the user.

Benefits:

● Reduces the risk of potential interference from Personal Radios and Low Frequency RF devices.

● Eliminates the risk of Static Electric discharges to critical on-board electronic components.

Options Consider:

EMI/ ESD Shielding

using:

Printed Ground Mesh

or

Carbon Flood
