TACT switches

Alps Electric has launched its new SKSG series TACT switch to meet the needs of compact and slim consumer devices in the market today with a cubic measure that is one third of its conventional products (2.7mm x 3mm x 1.4mm). The switches feature high operation force that protects against accidental operation, making it suitable for car AV equipment as well as keyless entry or car navigation systems.

Switches that function as operation buttons may only require a light operating force. However, there are instances where a high operation force is required, such as in remote control units for vehicle keyless entry systems. This prevents accidental operation when these devices are carried around inside pockets or bags. Additionally, controls found on car navigations systems and car audio equipment, as well as other digital devices make the user more aware of a button's operation when there is a distinct operation feel.

The TACT switch combines a high operation force of 4N with a long operating life of 200,000 cycles. A new metal contact (metallic board spring) was developed for the switch and Alps made full use of its quality engineering and analysis technology to create the contact's optimum configuration. Reducing the load against the metal contact when pressed achieves both high operation force and increases life span, creating a definite clicking sensation that helps prevent unintentional operation and reduces risk of failure over the life of the product.

Dimensional precision is not required when designing the set product as the switch is equipped with a stem. This makes product design easier while ensuring the switch's stable operation. Furthermore, the switch is also equipped with a ground function, which prevents static electricity from flowing into the set device, potentially causing operation failure and IC destruction.

A lighter operation force of 1.6N is also available in the series for use in general digital devices.

Sample shipments will commence from this month.
