Alps Electric has developed the SKSN series mid-mount TACT Switch. The switch is suitable for mobile devices like portable audio players and smart phones, to healthcare products such as blood glucose meters and pedometers. It has high strength and dust protection characteristics.

The switch is mounted into a PCB cut-out. This restricts the height of the switch above the PCB to 1.35mm, contributing to creation of small end products. It improves the strength of the mount in relation to the direction in which the switch is pressed. It also removes the need for a flexible or sub PCB for connecting switch and PCB, says the company.
Another feature is good impact resistance in the case of a product being dropped and dust-proof design incorporating a sealed contact structure and an insulator realises high dust protection. The stem is made to press the dome spring of the switch contact directly, providing a good operating feel during use, says the company.
