E-Switch – Soft-touch surface-mount tact switch offers long lifetime


E-Switch has announced the introduction of the TL9100 series of surface-mount tact switches which offers a soft-touch feel together with a long operating lifetime.

Provided in a Single- Pole, Single-Throw (SPST) configuration, the TL9100 series switches are available with an actuation-force rating of either 200gf or 350gf.

The operating lifetime of the switches depends on the force required to operate the device. The TL9100 switches configured with an operating force of 200gf are rated for 100,000 switching cycles, while the switches which have an operating force of 350gf are rated for 30,000 operations.
