ITT Industries, Cannon Introduces 2- and 4-Way Switches for Automotive, Industrial and Home Entertainment Applications

QSA series offers long life, excellent feedback and no click noise.

NEWTON, MA (February 24, 2004) -ITT Industries, Cannon offers new two- and four-way switches designed for long life, excellent tactile feedback and silent operation for use in a broad range of applications. Designated the QSA series, these devices were developed as a convenient control switch for products with low current demands of 1 - 50mA.

Unlike other switches on the market, which have a very noisy action, QSA devices are silent. QSA2 and QSA4 switches feature an actuation force of 3.5N +/- 1N with a force delta of greater than 0.5N and a return force of 1N thus providing excellent tactile feedback. Operational life is 100,000 operations.

Measuring 21x16x22.4mm, these surface mount switches can operate in either the X or Y axis. The actuator is on a 3.5mm diameter operating axis with a button fastener. Maximum switching power is 0.2VA, while operating temperature range is -40 to +85degC.

QSA switches cost around $1.30 in 100,000 piece range. Other applications include navigational GPS systems, joysticks for industrial control and off-road vehicles, and home entertainment equipment.
