Newton, Mass. ITT Industries, Cannon has introduced two- and four- way switches that are 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 to 50 milliamps (mA). Applications include navigational GPS systems, joysticks for industrial control and off-road vehicles, and home entertainment equipment.
Offering silent actuation, the QSA2 and QSA4 switches feature an actuation force of 3.5N ±1N with a force delta of greater than 0.5 N and a return force of 1 N to provide excellent tactile feedback, said the company. Operational life is 100,000 operations.
Measuring 21 x 16 x 22.4 mm, these surface-mount switches can operate in either the X or Y axis. The actuator is on a 3.5-mm diameter operating axis with a button fastener. Maximum switching power is 0.2 VA. The operating temperature range is -40°C to 85°C.
QSA switches are priced at approximately $1.30 each in quantities of 100,000.
