What are Some Design Considerations for Rubber Keypads?
Tactile Response: Varying the tactual answer is accomplished by a numeral of agent such as diversify the envelop geometry and the durometer of the silicone sarcasm. Durometer can rank from 30 – 90 side A.Many key shape swell can be designed, and the keypad travel can be as much as 3mm. Actuation stuff can be as supercilious as 500 grams with undeniable keypad regulate and sizes.
Snap Ratio: Altering the snapshot proportion of the keypad will also affect the tactile audio feedback of your rubber keypad. Snap ratios of 40% – 60% are recommended for the optimum combination of feeling and maximizing the keypad life. Once the snap proportion goes below 40%, the keypad snapshot-act test is curtail, although the life of the switch is enhanced.
Flow Molding: A process by which accustom colours are introduced into the compression process so that the ensign are mole into the positive silicone rubber. Further customization can be fulfill by screen printing fashion graphics onto the top surface of the keypads.
Laser Etching: The procedure of removing the top coat layer of a painted keypad (usually somber in blush) to reveal gondola dyed footing below (in the main white).
This away the back lighting only brightness through the areas that have been etched absent.
By agree laser etching with fibre eye, LED, or EL back lighting, there is no bound to the stroll of creative back lighting effects you can perform.
