TACT switches slim to compact applications
Alps Electric has released the industry's thinnest double-action TACT switches for applications such as shutter buttons for digital still and video cameras.
Detector switches seek automotive applications
The SPVQ4 Series comprises waterproof, high-contact-reliability detector switches that have a long stroke and can withstand severe conditions.
Resolution is a high 15 pulses or 30 detents per rotation, with detent torque of 5+/-3 or 10+/-5mNm.
The encoders are rated for voltages of 5V DC and have a maximum operating current of 5mA with resistive load.
Further technical specifications include an insulation resistance of 10Mohm at 250V DC, a voltage proof of 300V AC for 1min and a push-pull-strength of 100N.
The output signals of pins A and B are proportionate to the phase difference.
The centre push switch is a single-pole single-throw push-on device and is rated for switching currents of up to 1mA at 5V DC.
It requires an operating force of 3N (+1.5/-1.0N), and has an actuating travel of 0.5+/-0.3mm.
The maximum initial contact resistance is specified for 100mohm.
The vertically mountable EC12D series features a long operating life of up to 30,000 switching cycles or 15,000 rotational cycles.
The operating temperature ranges from -40 to +70C.
The encoders are housed in a compact body with external dimensions of only 12.5 x 11.7 x 5mm.
The switch body has an octagonal structure for smaller outline dimensions.
In addition, the octagonal shape allows the placement of LEDs for knob illumination much closer to the product.
Typical applications for the combined encoder/switch include volume and cursor control for in-car audio and navigation systems.
