Tiantai Electronics is a leading China non-tactile switch keypad manufacturer.
Non-tactile switch keypads are typically designed into a product due to one of the following reasons:
• Size Constraints: When there isn’t enough space for domes due the compact design.
• Light Activation Force: The customer wants to simply be able to run their finger over the key with a very light press in order to make contact i.e. does not want any snap when pressing the key.
• Non-tactile switch keypads are tougher and completely sheltered from the outside environment. This allows them to be rated for three times as many actuations as a tactile membrane switch.
Instead of the metal switch under the overlay, the non-tactile switch keypad uses a two-layer which
Consists of an upper & lower circuit which are separated by a spacer. Non-tactile switch keypads are very rugged, highly reliable and can be used in extreme weather environments.
